PAI Fuel Pump Check Valve

Eliminate hard starts and maintain consistent fuel pressure with the PAI Fuel Pump Check Valve. This precision-machined component is designed specifically for the Cummins N14 fuel gear pump, serving as the barrier that prevents fuel from draining back to the tank when the engine is off. The PAI 42211 valve features a calibrated internal spring and a durable seating surface that withstands the constant pulsation of the diesel lift pump. By ensuring the fuel galleys remain primed, this check valve allows for immediate firing during cold starts and consistent power delivery under load. Replacing a worn or leaking check valve is a cost-effective way to solve priming issues and protect your injectors from aeration.
