Description
Overview
The FASS Adjustable Diesel Fuel Lift Pump 180F is part of the FASS Signature Series ADJ Fuel System line, engineered to be one of the most versatile high performance fuel systems available for the Dodge Cummins 5.9L 12 Valve. Rated at 140 gallons per hour (140GPH) and tuned around 45 PSI, this adjustable system is built to meet the fuel demand of everything from a stock daily-driver to a moderately built race or competition truck making up to 700 HP.
This unit is manufactured with the same motor used in the FASS Titanium Signature Series systems, giving you proven pump performance in an adjustable package. With adjustable fuel pressure from 1-75 PSI, you can dial in fuel delivery precisely to match your engine’s needs, whether you’re chasing consistency on the street or maximizing supply at the track.
Key Benefits
Diesel engines live and die by clean, consistent fuel delivery. The FASS 180F improves fuel flow and lets you customize pressure to your application, while the built-in boost compensation port uses air pressure from your intake manifold to raise fuel pressure under full throttle — keeping fuel pressure where it belongs when it matters most. Whisper Technology helps keep operation quiet, and an integrated fuel pressure gauge port makes monitoring your system simple.

Set your pressure, take advantage of the boost compensation port, and let the system deliver steady, reliable fuel across the RPM range.
