Description
Description
The FASS Adjustable Series is the same fuel air separation architecture as the Titanium Signature Series, fitted with an adjustable fuel pressure regulator so you can dial outlet pressure to suit the build rather than living with a fixed setting.
Fits: Dodge RAM 2500 / 3500 Cummins, 1989-2014
Adjustable Pressure
The regulator is the difference. A stock truck, a mild tune and a competition build do not all want the same supply pressure, and on a fixed-pressure system your only options are the spring FASS shipped or a spring swap. Here you set it and move on.
