The ‘FAS’ Series from FASS Fuel Systems is the most versatile high performance aftermarket diesel fuel pump on the market today. Allowing drivers to make adjustments to the fuel pressure being delivered to the Cummins 5.9L & 6.7L diesel engine, without having to uninstall the pump, is unmatched by any competitor. A direct replacement for your Ram diesel pickups factory lift pump and manufactured with the same powerful motor from FASS Fuel Systems Titanium Series fuel pumps, this adjustable fuel pump is perfect for drag racers, sled pulling or high performance trucks looking to make real power.
As an added bonus FASS has included a boost compensation port, allowing you to increase fuel pressure temporarily while under heavy acceleration, keeping your fuel pressure consistent, based boost referencing from the turbo.
This is a fuel pump only and must be used with your factory fuel filter. It is suggested that all pumps be adjusted only if you have installed a fuel pressure gauge.
