Electric Fuel Pump This is the original Walbro electric fuel pump specified by the factory. It carries 48-52 PSI at .26 gallons per minute. Please avoid the automobile spec pump that looks similar. We have never tested one that carries more than 17 PSI. If you run out of power at full throttle, you need to check if you have the wrong pump. The pump body comes with a fuel filter that is different from our original, but works just fine. Also shown is the fuel pressure regulator available separately.
