Description

The FASS Adjustable Diesel Fuel Pump is engineered to be a versatile, high-performance solution for 2001-2016 GM Duramax 6.6L applications, particularly those with moderate to high performance modifications. This Signature Series pump boasts a flow rate of 165 gallons per hour and allows for precise fuel pressure adjustment from 1 to 20 PSI, enabling users to fine-tune fuel delivery for optimal performance in demanding race or competition environments. It incorporates a boost compensation port, which uses intake manifold air pressure to increase fuel pressure during full throttle operation, ensuring consistent fuel delivery when it's most critical. Manufactured with the same motor found in FASS Titanium Series pumps, this unit also includes a port for a built-in fuel pressure gauge and comes complete with all necessary mounting hardware for installation.
