Description
Overview
The FASS Fuel Systems Signature Series Adjustable Diesel Fuel Lift Pump is engineered to be one of the most versatile high-performance fuel systems available for the 2008-2010 Ford Powerstroke 6.4L. Built around the same proven motor found in the FASS Titanium Signature Series, this adjustable system (Part No. FASF16165G) is rated at a robust 165 gallons per hour and is designed to feed moderate to extreme builds in the 600-900 HP range.
Where a standard lift pump delivers a fixed pressure, this ADJ Fuel System Series unit gives you full command of your fuel curve. Adjustable fuel pressure from 1-20 PSI lets you dial in delivery to match the demands of a street truck, a race setup, or a full competition diesel engine. Constructed from durable 6061 T-6 billet aluminum in a clean black finish, it’s built to handle serious under-hood conditions while looking the part.
Key Benefits
Beyond raw volume, this system focuses on consistent, reliable fuel delivery. A built-in boost compensation port uses air pressure from your intake manifold to raise fuel pressure under full throttle, so pressure holds strong exactly when your engine is working hardest. FASS Whisper Technology keeps operation quiet, and an integrated fuel pressure gauge port makes it easy to monitor your system at a glance.
