Description
Overview
The FASS Fuel Systems Signature Series Adjustable Diesel Fuel Lift Pump (Part No. FASD07290G) 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 290 gallons per hour, this ADJ Fuel System Series unit uses the same proven motor found in the FASS Titanium Signature Series, but adds the adjustability that serious builds demand. With support for setups running up to 1200-1500 HP, it’s a highly modified solution built for trucks and SUVs that push hard.
Adjustable Fuel Pressure for Race and Competition
What sets this system apart is fully adjustable fuel pressure from 1 to 75 PSI. That range lets you dial in fuel delivery precisely to match your engine’s demands, whether you’re tuning for street performance, race duty, or all-out competition. Instead of settling for a fixed pressure, you customize the delivery to the build.
To keep fuel pressure consistent when it counts, FASS integrated a boost compensation port. As air pressure builds in your intake manifold under full throttle, it raises fuel pressure accordingly, maintaining reliable delivery at the exact moment your Cummins is working hardest.
Key Highlights
- 290 GPH flow capacity to feed high-horsepower Cummins builds
- Adjustable fuel pressure from 1-75 PSI for fully customized delivery
- Boost compensation port raises fuel pressure under full throttle
- Same motor used in the FASS Titanium Signature Series Systems
- Machined from durable 6061 T-6 Billet Aluminum in a black finish
- Sold as a complete kit including Bulkhead fitting and Suction Tube
Built to Last
Precision-machined from 6061 T-6 Billet Aluminum, this system is designed for durability and consistent performance. The included Bulkhead fitting is a smart, dual-purpose component that functions as both a suction tube and a return. It features a 5/8-inch Suction Tube along with a 1/2-inch Fuel Return Port, and represents a new and improved evolution over the previous FASS Suction Tube design.
What’s in the Kit
This is a complete kit, not a partial upgrade. It includes the Bulkhead fitting and Suction Tube so you have the core hardware needed to get the adjustable fuel delivery your build requires. The black finish gives the system a clean, purposeful look under the truck.
