2001-2010 GMC/Chevy 6.6L Duramax LB7/LLY/LBZ/LMM diesels do not come stock with a factory lift pump which means that the stock injection system has to perform the duty of both the lift pump and the injection pump, reducing the efficiency and performance output for the engine. By adding a FASS Flow Enhancer lift pump to help push fuel to the injection system, drivers will see a large improvement in horsepower and extended life on the injection pump.
