Proflow’s pro series 600LPH fuel pump is the perfect fuel pump to support any high horsepower street car or strip race car. Naturally aspirated, turbo or supercharged, this incredibly high flowing external fuel pump will support carburetted engines up to 1200HP and EFI engines up to 1000HP. Proflow’s PFEFS13110 4-Port fuel pressure regulator is a perfect match for this fuel pump in an EFI application, while PFEFS13204 can be used in a carburetted application. It is recommended to be mounted as low as possible relative to the fuel tank to ease priming and to avoid the pump running dry under W.O.T.Not compatible with diesel fuels.
