Description
Overview
The FASS Adjustable Diesel Fuel Lift Pump (ADJ Series, 180F 140GPH) is a Signature Series high performance fuel system engineered specifically for 1999-2007 Ford Powerstroke trucks and SUVs. Built around the same proven motor used in FASS Titanium Signature Series systems, this adjustable fuel system is designed for owners who need a fuel supply solution that can scale with their engine build, from a stock daily driver to a moderately built performance truck pushing up to 700 horsepower.
Housed in a 6061 T-6 billet aluminum body finished in black, this fuel system is built to hold up under the demands of high-pressure fuel delivery. Rated at 140 gallons per hour and 55 PSI, it delivers strong, consistent fuel flow while giving you the ability to fine-tune fuel pressure from 1-75 PSI to match your specific tune, injectors, and horsepower goals.
Key Benefits
Unlike fixed-pressure lift pumps, the ADJ Series gives you real control over fuel delivery. A built-in boost compensation port uses air pressure from your intake manifold to automatically raise fuel pressure under full throttle, so your engine gets the fuel it needs exactly when cylinder demand is highest. A built-in fuel pressure gauge port also lets you monitor system performance in real time without adding aftermarket fittings. FASS engineered this system with Whisper Technology for quieter operation compared to standard aftermarket lift pumps, so you get performance gains without unnecessary noise under the hood.
What’s Included & Fitment
This kit is sold complete with all mounting hardware included, simplifying installation on your 1999-2007 Powerstroke truck or SUV. Note that this is a fuel system only — it is designed to work in conjunction with your factory fuel filter and does not replace it. Because fuel pressure is adjustable, this system is versatile enough to serve a wide range of builds, from stock replacement duty to moderately modified performance applications rated 0-700 HP.
