Our -8 ORB to 1\/8\" NPT adapter fitting screws into the end of your fuel rail and gives you a 1\/8\" NPT port for your gauge or sensor. Most aftermarket fuel rails have -8 ORB ports on the ends. Most fuel pressure gauges and sensors use 1\/8\" NPT threads. This adapter converts the -8 ORB port on your fuel rail to 1\/8\" NPT so you can screw your gauge or sensor directly into your fuel rail.

The fitting comes with an E85-safe O-ring that seals the -8 ORB side to your fuel rail. If you're running E85 or you plan to run E85, the O-ring's compatible.

By installing this system, your 1.5 turbo Honda can safely and effectively increase power output to over 500 hp, with reliable engineering and thorough testing. The Hondata 1.5 fuel system accommodates customer-installed modifications such as turbo upgrades and flex fuel, which often require more fuel flow and can result in fuel limitations and boost limitations. With the Hondata fuel system, you can achieve maximum power and run full E85 fuel without any need for blending, while maintaining fuel pressure. This system has undergone rigorous testing over the course of several years and tens of thousands of miles.\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n 2017-2021 Honda Civic Si\u003cdiv\u003e\u003c\/div\u003e \n\u003c\/li\u003e\n\n\n\n\n\n\n \n\u003cli id=\"Included\"\u003e\n\u003cspan style=\"background-color: var(--rz-editor-content-background-color); color: var(--bs-body-color); font-size: var(--bs-body-font-size); text-align: var(--bs-body-text-align); font-weight: var(--bs-body-font-weight);\"\u003eHigh Flow Fuel Injectors \u0026amp; Clips\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"background-color: var(--rz-editor-content-background-color); color: var(--bs-body-color); font-size: var(--bs-body-font-size); text-align: var(--bs-body-text-align); font-weight: var(--bs-body-font-weight);\"\u003eHigh Flow High Pressure Fuel Line\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"background-color: var(--rz-editor-content-background-color); color: var(--bs-body-color); font-size: var(--bs-body-font-size); text-align: var(--bs-body-text-align); font-weight: var(--bs-body-font-weight);\"\u003eInjector Fly Leads\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"background-color: var(--rz-editor-content-background-color); color: var(--bs-body-color); font-size: var(--bs-body-font-size); text-align: var(--bs-body-text-align); font-weight: var(--bs-body-font-weight);\"\u003eCamshaft\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"background-color: var(--rz-editor-content-background-color); color: var(--bs-body-color); font-size: var(--bs-body-font-size); text-align: var(--bs-body-text-align); font-weight: var(--bs-body-font-weight);\"\u003eFlashPro software includes the mod for injector and camshaft support\u003c\/span\u003e\u003cbr style=\"color: var(--bs-body-color); font-size: var(--bs-body-font-size); text-align: var(--bs-body-text-align); font-weight: var(--bs-body-font-weight);\"\u003e\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\u003cli id=\"Warranty\"\u003e\n\u003cdiv\u003eThere is no warranty stated or implied due to the unusual stress placed on competition product(s) and\/or the inability to monitor their modification, installation, and use, unless otherwise stated.

The AEM high capacity adjustable fuel pressure regulator (part number 25-305BK) gives you stable, adjustable fuel pressure from 40 to 130 PSI. I've been running AEM regulators on my turbo Hondas for years because they actually hold pressure under boost without creeping. Your stock fuel pressure regulator's designed for 40-50 PSI and it can't handle high-flow pumps or high boost. When you're running a \u003ca href=\"https:\/\/www.hybrid-racing.com\/products\/walbro-450lph-e85-fuel-pump-high-pressure-variant?_pos=1\u0026amp;_sid=e12e1d8da\u0026amp;_ss=r\" target=\"_blank\"\u003eWalbro 450\u003c\/a\u003e or an Aeromotive pump with 1000cc injectors and 25+ PSI of boost, your stock regulator either creeps (pressure goes up when it shouldn't) or it can't flow enough fuel. The AEM regulator's got a huge return orifice that handles high pump flow without pressure creep, and it's got true 1:1 rising rate so your fuel pressure increases 1 PSI for every 1 PSI of boost.\u003c\/p\u003e\n\n\u003ch4\u003eHere's Why Stock Regulators Fail with Big Pumps\u003c\/h4\u003e\n\n\u003cp\u003eYour stock fuel pressure regulator's a simple spring-loaded valve. It's designed to maintain 40-50 PSI base pressure and rise 1:1 with boost. That works fine with a stock fuel pump flowing 200-300 liters per hour. But when you install a high-flow pump like a Walbro 450 (450 lph) or an Aeromotive pump (600+ lph), your stock regulator can't handle the volume. The return orifice (the hole where excess fuel goes back to the tank) is too small. When the pump's dumping 450 lph through a regulator designed for 250 lph, the regulator can't bypass enough fuel fast enough. Pressure creeps up at idle and cruise because the regulator's overwhelmed. You'll see 50 PSI at idle when you want 43 PSI, or pressure spikes to 60+ PSI on decel. That screws up your tune because your fuel trims are chasing a moving target. The AEM regulator's got a way bigger return orifice that handles high pump flow without creeping.\u003c\/p\u003e\n\n\u003ch4\u003e40-130 PSI Adjustment Range\u003c\/h4\u003e\n\n\u003cp\u003eThe AEM regulator adjusts from 40 to 130 PSI base pressure. Most people run 43 PSI base pressure (same as stock Honda fuel pressure) or 58 PSI for E85 setups. The adjustment screw on top lets you dial in your exact pressure. Once you set it, there's a set screw that locks the adjustment so it doesn't drift. I've seen cheap regulators where the adjustment drifts after a few heat cycles or vibration loosens it. The AEM regulator stays put once you lock it down. If you're running E85 or race gas and you need higher base pressure for injector flow, you can crank it up to 65-70 PSI. If you're running a returnless fuel system conversion, you can set whatever base pressure you want.\u003c\/p\u003e\n\n\u003ch4\u003eTrue 1:1 Rising Rate for Boost\u003c\/h4\u003e\n\n\u003cp\u003eThe AEM regulator's got a 1:1 rising rate when you connect it to a boost reference. That means for every 1 PSI of boost, your fuel pressure increases 1 PSI. If you're running 43 PSI base pressure and 20 PSI of boost, your fuel pressure at full boost is 63 PSI. That 1:1 rising rate keeps your injector differential pressure constant. Differential pressure is the difference between fuel pressure and manifold pressure. If fuel pressure rises 1:1 with boost, your injectors see the same pressure differential at 20 PSI boost as they do at vacuum. That means your injector flow rate stays consistent and your fuel table doesn't need boost-dependent corrections. Some cheap regulators don't maintain true 1:1, they creep or lag, and your tune gets messy.\u003c\/p\u003e\n\n\u003ch4\u003eWorks with E85, Race Gas, and Pump Gas\u003c\/h4\u003e\n\n\u003cp\u003eThe AEM regulator's compatible with gasoline, E85, methanol, and race gas. The internal diaphragm and seals are alcohol-resistant. If you're running E85 or methanol, you need higher fuel pressure to get enough injector flow because E85 needs 30% more fuel volume than gasoline. Most people running E85 set their base pressure to 58 PSI instead of 43 PSI. The AEM regulator handles that without any issues. I've run E85 through mine for years with zero diaphragm failures or seal degradation.\u003c\/p\u003e\n\n\u003ch4\u003e9\/16\"-18 Inlet and Return Fittings\u003c\/h4\u003e\n\n\u003cp\u003eThe regulator uses 9\/16\"-18 ORB (O-ring Boss) fittings on the inlet and return ports (Not included). That's a common AN fitting size. You're running -6 AN or -8 AN fuel lines from your fuel rail to the regulator inlet, and -6 AN return line from the regulator back to your fuel tank. The fittings use O-rings for sealing, not thread sealant or PTFE tape. The regulator also has a 1\/8 NPT gauge port where you can install a fuel pressure gauge or a fuel pressure sensor for your ECU. I always run a fuel pressure sensor so I can data log fuel pressure and catch problems before they grenade my engine.\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003eAEM high capacity adjustable fuel pressure regulator\u003c\/li\u003e\n  \u003cli\u003ePart number: 25-305BK\u003c\/li\u003e\n  \u003cli\u003eAdjustment range: 40-130 PSI base pressure\u003c\/li\u003e\n  \u003cli\u003eLarge return orifice (handles high-flow pumps without pressure creep)\u003c\/li\u003e\n  \u003cli\u003eTrue 1:1 rising rate with boost reference\u003c\/li\u003e\n  \u003cli\u003eInlet port: 9\/16\"-18 ORB (O-ring Boss)\u003c\/li\u003e\n  \u003cli\u003eReturn port: 9\/16\"-18 ORB (O-ring Boss)\u003c\/li\u003e\n  \u003cli\u003eGauge port: 1\/8 NPT\u003c\/li\u003e\n  \u003cli\u003eBoost reference port: 1\/8 NPT\u003c\/li\u003e\n  \u003cli\u003eAdjustment screw with set screw lock\u003c\/li\u003e\n  \u003cli\u003eCompatible with gasoline, E85, methanol, race gas\u003c\/li\u003e\n  \u003cli\u003eBlack anodized finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eWorks With\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003eHigh-flow fuel pumps (Walbro 255\/450, Aeromotive, DeatschWerks, etc.)\u003c\/li\u003e\n  \u003cli\u003eLarge injectors (800cc, 1000cc, 1200cc+)\u003c\/li\u003e\n  \u003cli\u003eTurbocharged and supercharged engines\u003c\/li\u003e\n  \u003cli\u003eE85, methanol, race gas fuel systems\u003c\/li\u003e\n  \u003cli\u003eReturnless fuel system conversions\u003c\/li\u003e\n  \u003cli\u003eUniversal fitment (works on any fuel system with -6 or -8 AN lines)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e This regulator requires a return fuel line back to your tank. If you're running a stock returnless fuel system, you'll need to install a return line or convert to a return-style fuel system. You can't use this regulator on a returnless system. The boost reference port connects to your intake manifold with a vacuum line. Make sure you're pulling boost reference from after your throttle body, not before. If you pull reference from your cold side piping before the throttle body, the regulator won't work right. When you're setting base fuel pressure, disconnect the boost reference line and adjust the screw with the engine at idle or with a fuel pressure gauge and pump prime. Don't set base pressure under boost or you'll set it wrong. The set screw locks your adjustment in place. Tighten it after you've dialed in your base pressure or the adjustment will drift from vibration. If you're running E85 and you want higher base pressure for injector flow, set it to 58 PSI. If you're running pump gas, set it to 43 PSI (stock Honda fuel pressure). Data log your fuel pressure if you can. Fuel pressure creep or drop-off under load means something's wrong with your fuel system.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n    Universal \n\u003c\/li\u003e\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\nAdjustment range: 40 – 130 PSI, single large return orifice\u003cdiv\u003e1:1 rising pressure rate\u003c\/div\u003e\n\u003cdiv\u003eThree 9\/16\"-18 ORB O-ring style inlet ports (2 inlet, 1 return)\u003c\/div\u003e\n\u003cdiv\u003e1\/8\" NPT gauge port, 5mm (3\/16\") vacuum hose\u003c\/div\u003e\n\u003cdiv\u003eCNC-machined from 6061-T6 billet aluminum\u003c\/div\u003e\n\u003cdiv\u003eCompatible with alcohol fuel and race gas\u003c\/div\u003e\n\u003c\/li\u003e\n\n\n\n \n\u003cli id=\"Included\"\u003e\n(1) Fuel Pressure Regulator\u003cdiv\u003e(1) Mounting Bracket\u003c\/div\u003e\n\u003cdiv\u003e(4) Mounting Bracket Screws\u003c\/div\u003e\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\u003cli id=\"InstallGuide\"\u003e\nInstall the regulator using the provided fittings and connect the vacuum hose.

Most fuel pumps are rated at free flow with no backpressure. That's useless. Your fuel system runs at 40-60 PSI base pressure, then it climbs 1:1 with boost. If you're running 20 PSI of boost on top of 50 PSI base pressure, your fuel pump's working against 70 PSI. A pump that flows 400 LPH at zero PSI might only flow 250 LPH at 70 PSI. That's not enough fuel for 500 whp and you're going lean at the top of the RPM range. AEM publishes actual flow numbers at actual pressure. This pump flows 400 LPH at 40 PSI, 340 LPH at 73 PSI, and 270 LPH at 120 PSI. You know exactly what you're getting at your operating pressure instead of guessing. This is a 60mm inline fuel pump that fits standard 044-style pump brackets. If you're already running an 044 bracket, this drops right in. The inlet's M18x1.5 female threads, the outlet's M12x1.5 male threads. If you're running AN fittings, you'll need adapters.\u003c\/p\u003e\n\n\u003ch4\u003eHere's Why Flow at Pressure Actually Matters\u003c\/h4\u003e\n\n\u003cp\u003eYour fuel system doesn't run at zero PSI. It runs at base pressure (usually 40-60 PSI depending on your regulator setting) plus boost pressure if you're running forced induction. If you're making 500 whp on a turbo motor at 20 PSI of boost with a 50 PSI base fuel pressure, your fuel pump's working against 70 PSI of backpressure. Most cheap fuel pumps lose 30-40% of their flow when you add that much backpressure. A pump rated at 400 LPH free flow might only flow 240-260 LPH at 70 PSI. That's not enough fuel. Your injectors are maxed out, your AFR's going lean, and you're detonating or you're pulling timing to stay safe. AEM publishes flow at actual pressure so you can size the pump correctly. At 73 PSI, this pump's still flowing 340 LPH. That's real flow at real pressure. You're not guessing if the pump can keep up. You know it can.\u003c\/p\u003e\n\n\u003ch4\u003eIt Fits 044-Style Brackets with Metric Ports\u003c\/h4\u003e\n\n\u003cp\u003eThis pump's 60mm diameter. That's the same size as a Bosch 044 pump. If you've already got an 044 bracket mounted in your car, this pump drops right in. Same bolt pattern, same clamp diameter. The difference is the ports. Bosch 044 pumps use AN fittings. This AEM pump uses metric threads. The inlet's M18x1.5 female (that's where fuel comes in from your tank or your pre-pump filter). The outlet's M12x1.5 male (that's where fuel goes out to your fuel rail). If you're running AN lines and AN fittings, you'll need metric-to-AN adapters. AEM sells them. Vibrant sells them. Radium sells them. Don't skip the adapters and try to force AN fittings onto metric threads. You'll strip the threads and trash the pump.\u003c\/p\u003e\n\n\u003ch4\u003eYou Need Real Wiring for This Pump\u003c\/h4\u003e\n\n\u003cp\u003eThis pump pulls serious current. At 40 PSI it's pulling about 10 amps. At 120 PSI it's pulling 17 amps. That's way more than your stock fuel pump wiring can handle. Stock fuel pump wiring's usually 16-gauge or 18-gauge wire with a 15-amp fuse. That's fine for a stock 80-LPH fuel pump pulling 5 amps. It's not fine for this pump. You need to run dedicated power and ground wires. Use 10-gauge or 12-gauge wire from the battery to a relay, then from the relay to the pump. Use a 25-amp fuse. Mount the relay close to the battery. Run a trigger wire from your stock fuel pump circuit to activate the relay. If you try to run this pump on stock wiring, you're going to get voltage drop. The pump's going to see 11 volts instead of 13.5 volts. Voltage drop kills flow. The pump won't flow what it's supposed to flow and you'll be chasing a lean condition that's caused by bad wiring, not a bad pump.\u003c\/p\u003e\n\n\u003ch4\u003eRated Power Numbers Are Guidelines, Not Guarantees\u003c\/h4\u003e\n\n\u003cp\u003eAEM says this pump supports 1,200 HP naturally aspirated or 860 HP at 30 PSI boost. Those are guidelines based on a generic engine with a generic BSFC (brake-specific fuel consumption). Your engine might be different. If you're running E85, your BSFC's higher and you need more fuel. If you're running a built engine with a lumpy cam and poor VE (volumetric efficiency) at low RPM, you might need more fuel at idle and cruise. If you're running a high-compression all-motor build with great VE, you might need less fuel. Don't just look at the horsepower number and assume the pump's big enough. Calculate your actual fuel flow requirement based on your horsepower, your BSFC, and your fuel type. If you're making 500 whp on E85 with a BSFC of 0.65, you need about 325 LPH at your operating pressure. This pump flows 340 LPH at 73 PSI. You've got headroom. If you're making 800 whp on E85, you need about 520 LPH. This pump won't cut it. You need two pumps or a bigger pump.\u003c\/p\u003e\n\n\u003ch4\u003eWhat You Get\u003c\/h4\u003e\n\n\u003cul\u003e\n  \u003cli\u003eAEM 400 LPH inline fuel pump (part number 50-1009)\u003c\/li\u003e\n  \u003cli\u003eFlow ratings: 400 LPH at 40 PSI, 340 LPH at 73 PSI, 270 LPH at 120 PSI\u003c\/li\u003e\n  \u003cli\u003e60mm diameter (fits standard 044-style pump brackets)\u003c\/li\u003e\n  \u003cli\u003eInlet: M18x1.5 female threads\u003c\/li\u003e\n  \u003cli\u003eOutlet: M12x1.5 male threads\u003c\/li\u003e\n  \u003cli\u003eRoller vane impeller with ceramic end plate\u003c\/li\u003e\n  \u003cli\u003eSteel body with black plating\u003c\/li\u003e\n  \u003cli\u003eInternal pressure relief valve (opens at 150 PSI)\u003c\/li\u003e\n  \u003cli\u003eVoltage range: 10V minimum, 18V maximum\u003c\/li\u003e\n  \u003cli\u003eCurrent draw: 10-17 amps depending on pressure\u003c\/li\u003e\n  \u003cli\u003eRecommended fuse: 25 amps\u003c\/li\u003e\n  \u003cli\u003eCompatible with gasoline, E85, E90 (pump life may be reduced on 100% alcohol)\u003c\/li\u003e\n  \u003cli\u003eWeight: 35.8 oz (1,015 grams)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e This is a universal inline fuel pump - you need to mount it externally with an 044-style bracket (not included). Inlet is M18x1.5 female, outlet is M12x1.5 male - if you're running AN fittings, you need metric-to-AN adapters (not included). This pump pulls 10-17 amps depending on pressure - you MUST run dedicated wiring with a relay, 10-gauge or 12-gauge wire, and a 25-amp fuse. Do not use stock fuel pump wiring or you'll have voltage drop and the pump won't flow correctly. AEM's power ratings (1,200 HP NA \/ 860 HP boosted) are guidelines - calculate your actual fuel requirement based on your horsepower, fuel type, and BSFC. This pump works with pump gas and ethanol blends including E85 - running 100% methanol or 100% ethanol may reduce pump life. Mount the pump below the fuel tank if possible so it's always primed with fuel.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n    Universal \n\u003c\/li\u003e\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\nFlows 400lph (105 gph) at 40 PSI, 340 lph (90 gph) at 73 PSI, and 270 lph (71 gph) at 120 PSI\u003cdiv\u003eOutside Diameter: 60mm OD\u003c\/div\u003e\n\u003cdiv\u003eExternal Materials: Plated steel\u003c\/div\u003e\n\u003cdiv\u003eInlet Fitting: M18X1.5 female\u003c\/div\u003e\n\u003cdiv\u003eOutlet Fitting: M12x1.5 male\u003c\/div\u003e\n\u003cdiv\u003ePRV Activation: 150 PSI\u003c\/div\u003e\n\u003cdiv\u003eImpeller: Roller vane with ceramic end plate.\u003c\/div\u003e\n\u003c\/li\u003e\n\n\n\n \n\u003cli id=\"Included\"\u003e\n(1) Fuel Pump\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\u003cli id=\"InstallGuide\"\u003e\nInstall the fuel pump using the provided hardware and check valve fitting.
