Description
Overview
The FASS Fuel Systems Signature Series Adjustable Diesel Fuel Lift Pump (Part No. FASD07250G) is engineered to be one of the most versatile high-performance fuel systems available for the Dodge Cummins platform. Purpose-built for the 2005-2009 Cummins Truck/SUV with the 5.9L and 6.7L engines, this Super Extreme system is rated for 900-1200 HP applications and delivers 250 gallons of diesel per hour (250GPH) to keep even the most demanding builds fed with clean, consistent fuel.
What sets this adjustable diesel fuel lift pump apart is its fully tunable fuel pressure. With an adjustable range from 1 to 75 PSI, you can dial in fuel delivery precisely for street, race, or competition diesel engines. It uses the very same motor found in FASS’s Titanium Signature Series systems, so you get proven pumping power alongside the flexibility to customize your setup.
Key Benefits
To keep fuel pressure stable when your engine is working hardest, FASS built in a boost compensation port. Air pressure drawn from your intake manifold raises fuel pressure under full throttle, maintaining delivery at the exact moment your engine demands it most. This is the kind of engineering detail that separates a purpose-built performance fuel system from a basic replacement pump.
Machined from 6061 T-6 Billet Aluminum and finished in black, this system is designed to hold up to the rigors of high-horsepower diesel use. The included billet Bulkhead fitting functions as both a suction tube and return, featuring a 5/8-inch Suction Tube paired with a 1/2-inch Fuel Return Port. This new and improved design is an upgrade over the previous suction tube setup, giving you reliable fuel pickup and return in one component.
