The fuel pressure regulator lives inside the tank module, and one line feeds the engine. Fuel pressure is set at the tank, and the rail just gets whatever comes up the line. That's simple and works fine at stock power. But it doesn't hold up well to boost. A boosted engine needs fuel pressure that rises with boost to keep the injectors flowing, and a regulator sitting back in the tank can't see boost pressure at all. Add more fuel demand on top of that, and the factory pump and single line run out of room quickly.\u003c\/p\u003e\n\u003cp\u003eThe DW400 module fixes both problems. It's built around a DW400 pump and switches the car to a return-style system. A new -6AN line carries fuel up to the engine, and the factory feed line gets reused as the return. That lets you put a regulator up in the engine bay where it can reference boost. DeatschWerks rates it for up to 900 hp on gasoline and 700 hp on E85, which is far more than any K20Z3 build will ask of it. You're not buying it for the horsepower number. You're buying it so a turbo Si gets steady fuel pressure that rises with boost, and you won't have to replace your fuel system again when the power goes up.\u003c\/p\u003e\n\u003ch4\u003eKeeps What the Factory Module Did Right\u003c\/h4\u003e\n\u003cp\u003eIt drops into the tank in place of the factory module and keeps the two features that matter most. First, the fuel level sender, so your gas gauge still works. Second, the surge bucket. That's a cup around the pump inlet that holds fuel there when the tank is low and you're cornering hard, so the pump doesn't suck air. The harness connector plugs into your factory wiring. Hoses, clamps, filters, and the electrical connector are all included, so you're not hunting for small parts mid-install.\u003c\/p\u003e\n\u003ch4\u003eCPE or PTFE Return Kit?\u003c\/h4\u003e\n\u003cp\u003eThe module comes on its own, or with one of two return line kits. Both include a regulator and filtration. The CPE kit uses CPE fuel hose, a synthetic rubber made to handle gasoline and E85. It's the affordable choice for most builds. The PTFE kit uses PTFE-lined hose with push-to-fit connections. PTFE is basically inert to fuel, so it won't break down in ethanol over time, and it lets far less fuel vapor through the hose wall. That means less fuel smell in the garage. If you're running E85 full time, the PTFE kit is worth the extra money.\u003c\/p\u003e\n\u003ch4\u003eInstall Notes\u003c\/h4\u003e\n\u003cp\u003eRun the tank low and depressurize the system before you pull the factory module from under the rear seat. Use a new module-to-tank seal if the old one is hard or flattened. Route the new -6AN feed line away from exhaust heat and moving suspension parts, and secure it along the body. Once it's all together, check for leaks with the key on and the pump running before you start the car. A higher-flow pump also draws more current, so check the voltage at the pump with the engine running. If it's down more than a few tenths of a volt from the battery, add a dedicated relay and new wiring. Once the regulator's in, have the car tuned for the new fuel pressure.\u003c\/p\u003e\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e2006-2011 Honda Civic Si coupe and sedan (FG2\/FA5) - K20Z3\u003c\/li\u003e\n\u003cli\u003e2008 Honda Civic Mugen Si - K20Z3\u003c\/li\u003e\n\u003cli\u003eDoes not fit non-Si 2006-2011 Civics\u003c\/li\u003e\n\u003cli\u003eConverts to a return-style fuel system: -6AN feed, factory feed line reused as return\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003cp\u003e\u003cspan class=\"tag\"\u003e2006-2011 Honda Civic Si\u003c\/span\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003cp\u003e\u003cspan class=\"tag\"\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cbr\u003e \n\u003c\/li\u003e\n\n\n\n\n\u003cli id=\"TechnicalData\"\u003e\n\n\u003c\/li\u003e\n\n\n\n \n\u003cli id=\"Included\"\u003e\n\n\u003c\/li\u003e\n\n\n\n\n\n\n\n\n\n\n\n\u003cli id=\"InstallGuide\"\u003e\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n","brand":"DeatschWerks","offers":[{"title":"Pump Module Only","offer_id":69706210869282,"sku":"DTW-9-401-7041","price":539.0,"currency_code":"USD","in_stock":false},{"title":"Pump Module + CPE Return Kit","offer_id":69706210902050,"sku":"DTW-9-401-607-7041","price":1049.0,"currency_code":"USD","in_stock":false},{"title":"Pump Module + PTFE Return Kit","offer_id":69706210934818,"sku":"DTW-9-401-608-7041","price":1179.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/16874956.jpg?v=1794242632","url":"https:\/\/www.hybrid-racing.com\/products\/deatschwerks-dw400-pump-module-for-06-11-civic-si-kits-available","provider":"Hybrid Racing","version":"1.0","type":"link"}
