Description
Overview
The FASS Adjustable Diesel Fuel Lift Pump delivers 290GPH of clean, consistent diesel to your 2010-2014 Dodge Cummins 6.7L. Part of the FASS Fuel Systems Signature Series Adjustable Fuel System lineup, this kit is engineered to be one of the most versatile high-performance fuel systems available, giving you full control over fuel pressure to match the demands of aggressive high-horsepower and competition builds. Configured in the Highly Modified HP form for 1200-1500 HP applications, it uses the same proven motor found in the FASS Titanium Signature Series Systems.
Adjustable Pressure & Boost Compensation
Where a fixed-pressure pump forces you into a single tune, this adjustable fuel system lets you dial in fuel pressure anywhere from 1 to 75 PSI, so you can customize fuel delivery precisely for race, competition, or street-driven diesel engines. A built-in boost compensation port takes it a step further: air pressure drawn from your intake manifold raises fuel pressure under full throttle, maintaining consistent supply exactly when your engine demands it most. The result is dependable fuel delivery across the full RPM range, with the flexibility to grow alongside your build.
Built to Last
Machined from 6061 T-6 Billet Aluminum and finished in black, this pump is designed for durability under the harsh conditions of high-performance diesel use. Sold as a complete kit, it includes a bulkhead fitting and suction tube. The bulkhead fitting functions as both a suction tube and return, featuring a 5/8-inch suction tube alongside a 1/2-inch fuel return port. This new and improved suction tube design allows you to plumb your FASS return cleanly and efficiently, improving on the previous version.
