Show original supplier description
The FASS FAS C09 100G-FASS is a Signature Series adjustable diesel fuel lift pump engineered for high-performance 2001-2016 GM 6.6L Duramax applications, supporting stock to moderate horsepower levels (0-600 HP). This pump is manufactured with the same motor found in their Titanium Signature Series pumps and offers a flow rate of 100 gallons per hour. It provides adjustable fuel pressure ranging from 1-20 PSI, allowing customization for race or competition engines. For optimal performance under full throttle, it includes a boost compensation port that uses intake manifold air pressure to maintain consistent fuel pressure. Key features include FASS's Whisper Technology for quieter operation, an integrated fuel pressure gauge port, and all necessary mounting hardware. This product is a fuel pump only and requires the use of the factory fuel filter. It is strongly recommended to only adjust the fuel pressure if a fuel pressure gauge has been installed.
