Description
Overview
The FASS Fuel Systems Signature Series Adjustable Diesel Fuel Lift Pump (Part No. FASF16290G) is engineered to be one of the most versatile high-performance fuel systems available for the 6.7L Ford Powerstroke. Built around the same proven motor found in the FASS Titanium Series, this adjustable system delivers a robust 140 gallons per hour and lets you dial in fuel pressure to match everything from a daily-driven stock truck to a serious race or competition build. It ships as a complete kit with all mounting hardware included.
Where a fixed-pressure pump forces you into one setting, this ADJ Fuel System Series unit puts you in control. The fully adjustable pressure range of 1–75 PSI (55 PSI reference rating) means you can customize fuel delivery to the exact demand of your engine, supporting stock to moderate applications in the 0–700 HP window.
Key Benefits
FASS designed this system to improve fuel flow while running quietly thanks to Whisper Technology, so you gain performance without added drivetrain noise. A built-in boost compensation port takes air pressure from your intake manifold and raises fuel pressure under full throttle—maintaining consistent fuel delivery precisely when your engine needs it most. A dedicated fuel pressure gauge port makes it easy to monitor your setup and verify your adjustments.
Constructed from 6061 T-6 billet aluminum with a black finish, the housing is built to hold up in the demanding environment of a diesel fuel system. The billet body pairs durable materials with the high-output FASS motor to keep clean, consistent fuel moving to your engine.
