Description
Overview
The FASS Adjustable Diesel Fuel Lift Pump 290F is part of the FASS Fuel Systems Signature Series ADJ Fuel System line, engineered to be one of the most versatile high-performance fuel systems available for demanding Ford Powerstroke applications. Rated at 240 gallons per hour (240GPH) and capable of delivering fuel pressure at 55 PSI, this adjustable system is built to feed serious diesel builds in the Super Extreme 900-1200 HP range. It uses the same proven motor found in the flagship Titanium Signature Series systems, so you get top-tier fuel delivery in a package designed specifically for race and competition-minded trucks.
Adjustable Performance
What sets this system apart is its adjustability. Fuel pressure can be dialed in anywhere from 1 to 75 PSI, letting you customize fuel delivery to match the exact demands of your high-performance Powerstroke engine. Whether you’re fine-tuning for the street or maximizing output for competition, the adjustable pressure range gives you full control over how fuel reaches your engine.
To keep fuel pressure consistent when it counts, FASS built in a boost compensation port. As air pressure builds in your intake manifold under full throttle, that boost signal raises fuel pressure accordingly — maintaining reliable fuel delivery during the exact moments your engine demands it most.
Built to Last
Durability is engineered in from the start. Key components, including the Bulkhead fitting, are machined from rugged 6061 T-6 Billet Aluminum and finished in black. The Bulkhead functions as both a suction tube and return, featuring a 5/8-inch Suction Tube alongside a 1/2-inch Fuel Return Port. This improved suction tube design refines fuel pickup and return over previous versions for cleaner, more consistent fuel delivery.
Sold as a Complete Kit
This is sold as a complete kit and includes both the Bulkhead and Suction Tube, giving you the core components needed to integrate the system into your fuel setup. The Signature Series ADJ platform is designed to be the versatile, high-performance backbone of your diesel fuel system.
