DeatschWerks 265lph Fuel Pump for 06-11 Honda Civic

DeatschWerks 265lph In-Tank Fuel Pump - 2006-2011 Honda Civic (8th Gen)

Your 8th-gen Civic runs a returnless fuel system. The pump, filter, and pressure regulator all live in a module inside the tank, and only one line runs up to the engine. The pump is sized for factory power with a little margin. That's fine on a stock car, but there isn't much room left over. Add a turbo or supercharger to an R18 or K20Z3, or blend in ethanol, and the engine needs more fuel than the stock pump can comfortably deliver at full throttle. Once that happens, fuel pressure sags under load and the engine goes lean exactly when it's working hardest. Factory pumps on cars this old are also starting to fail from wear, so many owners are replacing them anyway.

The DeatschWerks pump drops into the factory module and flows 265 liters per hour, about 70 gallons per hour. That gives a lightly boosted Civic or an ethanol blend the headroom it needs, and it's a solid replacement if your factory pump is on its way out. A stock N/A Civic won't run any differently with it, since the factory pump was already keeping up. It's a good choice if you're boosting the car or the old pump needs replacing anyway.

Built to Drop Into the Factory Module

The pump body is 65mm across, the same as the factory pump, so it fits into the factory module without any trimming. It uses your stock wiring and connects without adding any rubber fuel line, so you're not adding a hose clamp inside the tank that could leak later. Inside, it has a turbine impeller. That's a spinning disc with a ring of small blades around the edge, and it moves fuel smoothly instead of in pulses. That's why it runs quiet. You won't hear a whine from the back seat at a stoplight.

Ethanol Compatible

Ethanol is hard on pump internals that weren't built for it. DeatschWerks rates this pump as ethanol compatible, so it's a good match for an ethanol blend. If you're going that route, remember the injectors and tune also have to be able to supply the extra fuel ethanol needs. The pump alone doesn't fuel the car. The pump comes with a 3-year no-fault warranty.

Install Notes

Depressurize the fuel system before you open anything, and run the tank low so there's less fuel to deal with when you pull the module. Access is under the rear seat. Swap the pump into the module carefully. Don't kink the level sender arm, and keep the filter sock clean. Use a new module-to-tank seal if the old one is hard or flattened. Before you start the car, turn the key to on a few times and check for leaks at the module.
