Description
Overview
The FASS Adjustable Diesel Fuel Lift Pump (Part No. FASF16290G) is a Signature Series ADJ Fuel System built for 2011-2016 Ford Powerstroke 6.7L trucks and SUVs. Engineered by FASS Fuel Systems, this adjustable fuel system uses the same motor found in the Titanium Series lineup, delivering a rated 140GPH of diesel fuel flow with fuel pressure adjustable from 1-75 PSI. Housed in a durable 6061 T-6 billet aluminum housing finished in black, this unit is designed for owners who demand consistent, tunable fuel delivery whether running stock power levels or pushing into moderate performance territory.
Rated for Stock to Moderate 0-700 HP applications, this system ships as a complete kit and is intended to replace or supplement your factory fuel delivery setup as a fuel system only — it must be used with your factory fuel filter. The 55 PSI baseline rating combined with the wide adjustability range gives tuners and truck owners the flexibility to dial in fuel pressure to match specific tuning demands, injector requirements, or towing needs.
Key Benefits
One of the standout features of this FASS system is the boost compensation port. As boost pressure builds in the intake manifold under full throttle, that pressure signal raises fuel pressure in real time, helping maintain adequate fuel delivery exactly when the engine needs it most — under load and at high RPM. A built-in fuel pressure gauge port also makes it simple to monitor pressure directly at the pump, so you always know your system is performing as expected. FASS’s Whisper Technology keeps operation quiet, and all mounting hardware is included for a complete installation.
Build Quality & Design
Constructed from 6061 T-6 billet aluminum, the housing is built to withstand the demands of daily driving, towing, and performance use. The adjustable design means this single fuel system can serve a range of power goals, from a stock daily driver to a moderately built 6.7L Powerstroke pushing up toward 700 HP, without needing to swap to a different fixed-pressure unit as your setup evolves.
