Description
Overview
The FASS Adjustable Diesel Fuel Lift Pump 290F is a Signature Series ADJ Fuel System built by FASS Fuel Systems for 1999-2007 Ford Powerstroke trucks and SUVs. Engineered for high performance and competition-grade diesel applications, this Super Extreme 900-1200 HP rated system delivers 240 gallons per hour (240GPH) at 55 PSI, giving your Powerstroke the volume and pressure it needs to keep pace with aggressive tuning, larger injectors, and increased fuel demand. Sold as a complete kit, this adjustable fuel system is designed to be one of the most versatile high performance fuel delivery solutions available for Ford Powerstroke platforms.
Adjustable Performance Built for Serious Power
Unlike fixed-pressure lift pumps, this Signature Series system offers adjustable fuel pressure from 1-75 PSI, allowing you to dial in fuel delivery to match the specific demands of your race or competition diesel engine. This adjustability makes it a smart choice for builds that evolve over time, from moderate power gains to full-throttle, high-horsepower applications. A built-in boost compensation port takes air pressure from the intake manifold and uses it to raise fuel pressure under full throttle, so fuel delivery is maintained precisely when the engine needs it most.
Construction & Included Components
The kit includes a Bulkhead and Suction Tube, both machined from 6061 T-6 billet aluminum for strength and durability under demanding conditions. The billet bulkhead fitting does double duty, functioning as both a suction tube and return, and is equipped with a 5/8 inch suction tube along with a 1/2 inch fuel return port. This improved design over previous suction tube setups is finished in black for a clean, factory-quality appearance under the hood.
Fitment
This FASS Adjustable Fuel System is designed to fit 1999-2007 Powerstroke trucks and SUVs, making it a direct-fit solution for owners running 7.3L and 6.0L Powerstroke platforms within this model range.
