The Cummins Fuel Discharge Pipe 4994932 is a precision-engineered fuel system component designed to carry high-pressure diesel fuel from the injection pump to the injectors in Cummins B4.5, B5.9, and B6.7 engines. Proper fuel delivery at correct pressure is essential for efficient combustion, engine power, and emissions control.
Manufactured to OEM specifications, this fuel discharge pipe is constructed from high-strength materials capable of withstanding extreme fuel pressure, engine heat, and constant vibration. The exact-fit design ensures secure connections, minimizes pressure loss, and reduces the risk of fuel leakage during operation.
A damaged or worn fuel discharge pipe can lead to fuel leaks, reduced injection pressure, poor engine performance, excessive smoke, or injector damage. Replacing it with the Cummins 4994932 fuel discharge pipe restores proper fuel flow, improves combustion efficiency, and supports long-term engine reliability. This component is ideal for routine maintenance, fuel system repairs, and complete engine rebuilds across commercial, industrial, agricultural, and off-highway diesel applications.
