This 100 Gallon Per Hour lift pump from Fass Fuel Systems is a must - have upgrade for 2001 - 2010 GM/Chevrolet 2500HD/3500HD trucks with 6.6L Duramax engines. Unlike other diesel trucks, Duramax doesn't come with a lift pump from the factory. Using the CP3/CP4 injection pump to pull fuel under a vacuum adds stress to the injection pump and risks air in the fuel. With this FASS system, fuel is pumped to the CP3, reducing stress on the injection pump and providing better - quality fuel, which extends the life of most fuel system components. It has a power rating from stock to 600HP, a preset fuel pressure of 8 - 10PSI, a flow rating of 100GPH, a filter life expectancy of 30,000 miles, and a 2 - micron filtration rating. Features include new Whisper Technology, bolt - on bracket installation, a full supply system, water/air/debris removal, a fuel pressure gauge port, and many more. It comes with a limited lifetime warranty and a 1,000,000 - mile motor. FASS Whisper Technology reduces sound levels while increasing fuel flow. The new bolt - on brackets simplify installation using the Duramax factory bed bolt. Performance Radius Cuts in the FASS system improve fuel flow. Part Number: TSC10100G. Installation on a cab and chassis may require modifications.

Using this lift pump is quite straightforward. First, find a suitable place to install it on your Duramax truck. Thanks to the new bolt - on brackets, installation is quick and easy, just use the factory bed bolt. After installation, connect the ½ - inch fuel lines and ports properly. For normal use, the pump will automatically work to pump fuel to the CP3 injection pump, reducing its stress. Regarding maintenance, keep an eye on the filter. It has a life expectancy of 30,000 miles, so replace it regularly to ensure good filtration. Also, check the fuel pressure gauge if you have one. The preset fuel pressure is 8 - 10PSI, and any significant deviation might indicate an issue. Note that if you have a cab and chassis, installation may need some modifications. This lift pump comes with a limited lifetime warranty, so if you face any problems, don't hesitate to contact the manufacturer.
