PPE 113061100 Dual Fueler Install Kit with CP3 Pump | 2001 GM Silverado/Sierra 2500HD/3500HD 6.6L Duramax LB7

Features: - New BOSCH CP3 pump with heavy duty hardware - Bolt on installation - Billet aluminum drive pully with 6 V grooves - Retains factory safety pressure relief valve - 1-year limited warranty Precisely Fuels Your Engine Designed to easily bolt on to your Duramax, the Dual Fueler Install Kit w/ CP3 Pump offers precise fuel delivery. PPE's belt-driven Bosch CP3 fuel pump kit works in conjunction with the stock fuel system and is controlled by a sophisticated microprocessor module for seamless operation. Adding Reliability to the Fuel System Adding PPE's kit to your stock fuel system reduces drive load on the stock CP3 pump, thereby increasing pump reliability. Both pumps work together, each delivering half the total volume of fuel required. In the event of one pump failing the electronic controller will automatically switch all fuel delivery responsibilities to the remaining operational pump. This kit will not produce more fuel pressure than the engine ECU requests; it will only increase fuel volume as needed to maintain ECU requested fuel pressure. Fits:2001 GM 6.6L Duramax LB7
