Starve a VP44, a P7100 or a CP3 of inlet fuel and you do not merely lose power — you shorten the life of the most expensive part on the engine, which is why a failing lift pump so often takes the injection pump with it. Falling supply pressure shows up as hard starting, a stumble or surge under load, a miss at highway speed and power that fades as the tank empties. A fresh pump of the correct pressure and flow rating restores steady inlet supply and protects the injection system.\u003c\/p\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ea fuel lift or transfer pump matched to the engine as specified\u003c\/li\u003e\n\u003cli\u003ethe mounting gasket, seals and fittings where the pump includes them\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cp\u003eFits Chevrolet, GMC trucks equipped with the LLY Duramax diesel engine, 2004.5-2005.
