Check Valve


The check valve assembly (HI) has a return flow passage measuring O.36 mm (0.0142 in) in diameter. This port prevents excessive enrichment of the fuel/ air mixture by fuel dispensed by the fuel pump during acceleration, that is, depending upon the speed with which the throttle pedal is depressed, larger or smaller amounts of fuel are permitted to flow back to the pump.
