Description
Overview
The FASS FASC09250G Adjustable Diesel Fuel Lift Pump is part of the FASS Signature Series Adjustable Diesel Fuel Systems, engineered to be one of the most versatile high-performance fuel delivery systems available for the GM Duramax 6.6L. Built for the 2001-2016 Duramax truck and SUV platform, this Super Extreme system supports 900-1200 HP applications and is rated to move 250 gallons of diesel fuel per hour, giving serious builds the volume they demand.
What sets this ADJ Fuel System Series apart is its fully adjustable fuel pressure, dialing in anywhere from 1 to 75 PSI. That range lets you customize fuel delivery precisely for race or competition diesel engines, matching pressure to the exact needs of your combination rather than settling for a fixed output. The pump uses the same proven motor found in the FASS Titanium Signature Series Systems, so you get flagship-grade performance in an adjustable package.
Key Benefits
To keep fuel pressure consistent where it counts, FASS built in a boost compensation port. Air pressure drawn from your intake manifold raises fuel pressure under full throttle, maintaining delivery during the moments your engine is working hardest. This is exactly the kind of feature high-horsepower Duramax owners rely on when pushing their trucks to the limit.
Sold as a complete kit, the FASC09250G includes a bulkhead fitting and suction tube so you have the core components needed for installation. The bulkhead fitting is machined from 6061 T-6 Billet Aluminum for strength and durability, and it functions as both a suction tube and return. It features a 5/8-inch suction tube alongside a 1/2-inch fuel return port, and this new and improved design over previous suction tubes gives you added flexibility to plumb your FASS return the way your setup requires.
