Your Cart is Empty
This drop-in replacement fuel pump from Walbro supplies up to 450 liters per hour of fuel flow. It's a must if you go with a larger turbocharger. It's made in the U.S.A., and we can tell you these things are nearly bullet-proof. (Well, not LITERALLY bullet-proof. But you get the idea.)
The included installation kit includes a fuel sock (filter), wiring harness, rubber adapter thing, and even a couple of new clamps. Note that on some late-model Subarus you will NOT be able to use the provided sock, and will have to use the original one that's in the car.
Note that this is an extremely high-flowing pump, and we highly recommend aftermarket fuel pressure regulator, fuel injectors, lines, and rails, not to mention custom ECU tuning to take advantage of the extra fuel flow.
Installation is straightforward, but since you're dealing with the fuel tank and potentially explosive vapors, we highly recommend you have it installed by a professional mechanic.
Fits all 2002-2007 Subaru WRX and WRX STI.
