DeatschWerks K Series Black Fuel Rail for Honda/Acura

DeatschWerks Black Fuel Rail for K Series

If you’re leaning on your K-Series harder than stock, the factory rail starts feeling like the weak link. This DeatschWerks K-Series Fuel Rail, SKU: DTW-7-402, gives you a solid foundation for common K swaps and builds, It’s a black anodized fuel rail with the ports you actually use, and it bolts on clean when you’re building a Honda returnless fuel rail setup or converting to a return system.

You get integrated mounting brackets, so the rail stays put when you’re wrenching on lines and fittings, and when the car’s vibrating at 8000 rpm. DeatschWerks includes a 3/8 NPT port for a fuel pulsation damper, plus a 1/8 NPT port if you want to add a sensor or run a nitrous feed. It’s built from 6061 T6 aluminum and finished in hard anodized matte black, which helps with corrosion resistance and plays nicer with alternative fuels than bare aluminum. We run these on our own cars because they’re simple, sturdy, and they don’t turn into a science project halfway through your install.

Key Features

• Integrated Mounting Brackets: Keeps everything rigid, no sketchy flex or stress on fittings.
• Flexible NPT Ports: 3/8 NPT for a damper, 1/8 NPT for sensors or nitrous.
• Corrosion Resistant Hardware: Stainless hardware, so you’re not chasing rusty fasteners later.
• Fuel Compatibility: Hard anodized finish for ethanol and other alternative fuels.
• Injector Adaptability: Works with OE injectors and DeatschWerks EV14 injectors.
• System Compatibility: Supports returnless and return fuel systems.
• Matte Black Finish: Looks right in a clean bay, especially on swapped cars.
• Efficient Flow Design: Prioritizes consistent feed to the injectors, especially useful at higher demand.

In the box you get the rail, mounting hardware, and an OEM fuel line adapter fitting. Heads up, depending on your intake manifold, you may need to remove OEM fuel rail spacers. That’s normal with K series manifold variation, not a defect.

Fitment covers the usual hits for an Accord, RSX, TSX , Civic Si, CR-V, and Element applications across multiple years. If you’re building a reliable K-series setup that you can actually service, this DeatschWerks fuel rail is the kind of part you install once and stop thinking about, which is exactly the point.
