Description
Overview
The FASS Fuel Systems Signature Series Adjustable Diesel Fuel Lift Pump (Part No. FASD07165G) is engineered to be one of the most versatile high-performance fuel systems available for the 2005-2009 Dodge Cummins 5.9L and 6.7L. Rated at 165 gallons per hour, this ADJ Fuel System Series pump is built around the same proven motor found in the Titanium Signature Series, delivering the volume and reliability that serious diesel builds demand.
Where standard lift pumps lock you into a fixed output, this adjustable system puts fuel pressure in your hands. With an adjustable range from 1-20 PSI, you can dial in fuel delivery precisely for street, strip, race, or full competition applications, making it an ideal match for moderate to extreme setups in the 600-900 HP range.
Key Benefits
Performance diesels are hungry, and fuel pressure that sags under load can leave power and safety on the table. FASS addresses this directly with a built-in boost compensation port. Air pressure drawn from your intake manifold raises fuel pressure under full throttle, so your engine maintains consistent fuel delivery exactly when it matters most, during wide-open, high-boost pulls.
Machined from 6061 T-6 Billet Aluminum and finished in black, the system is designed to hold up to the demands of high-output Cummins applications while giving you the tunability to match your combination.
What’s in the Kit
This is sold as a complete kit and includes a Bulkhead fitting and Suction Tube to simplify installation. The billet aluminum Bulkhead fitting cleverly functions as both a suction tube and a return, featuring a 5/8 inch Suction Tube along with a 1/2 inch Fuel Return Port. This new and improved design refines the previous suction tube setup for a cleaner, more efficient fuel pickup and return solution.
