FASS has done it again — with their Adjustable Fuel Pump Series, the most versatile high performance fuel pump available. Unlike most FASS pumps, the Adjustable Fuel Pump does just one job and does it well – It keeps fuel pressure in line with the needs of your diesel engine. This 125 GPH fuel pump supports diesel engines with stock to moderate horse power needs.
Providing consistent, high performance improvements to your diesel’s fueling, the Adjustable Fuel Pump allows you to tweak the fuel pressure “on-the-fly”, giving you the ultimate in user control. These pumps are preset at about 60 psi. Using a simple 1/8" Allen plug, you can make a quick clockwise adjustment to increase pressure or counter clockwise adjustment to decrease pressure.
The Boost Compensation Port also gives the pump added and more consistent fuel pressure based on boost referencing from the turbo, keeping fuel pressure in line with the needs of the engine. A fuel pressure gauge is highly recommended to identify fuel filter life and to prevent engine damage. Give your diesel engine the fuel it needs today with the all new FASS Adjustable Fuel Pump.

FASS is in the business of building extremely High-Quality fuel products. All of their efforts are concentrated in this one area. FASS takes great pride in this specialization and implements rigorous testing procedures for each FASS product so you can share this same pride — that you are running with the Highest-Quality fuel system in the world.

Suction Line Notes: Due to the increase of fuel flow you may encounter a problem with the stock fuel module. Adding an optional FASS suction tube kit (STK-1002) will solve that issue.

FASS Fuel Systems has over 19 years experience in building the “Quietest” highest quality Fuel Air Separation Systems and electric diesel fuel pumps available worldwide. It is this experience, they say, that leads them to use a Gerotor specific fuel pump. Their success in the class 8 truck market has unstoppable. Their pumps typically last at least 700,000+ miles and the confidence is evident in their warranty — Offering warranties from 4 years on semi’s up to a lifetime warranty on pickup’s applications!
With over 90% of the machining, and 100% of the assembly and testing performed under one roof, they’ve been able to maintain the highest quality standards throughout the industry. The FASS systems undergo over 20 vigorous tests before being shipped to insure quality and performance.
With an on-site R&D department working to continually exceed your expectations, FASS uses one of the highest grades of Aircraft Quality Billet 6061 T-6 Aluminum, as a major component along with motor specific brushes in their electric motors to maintain the same high quality standard and increase the overall life of their units. Due to the brute size of their motor armatures, they are able to achieve superior levels of stall torque. This increased amount of stall torque insures extreme cold weather starts by flowing gelling fuel.
