Choose your flow rate below; every option on this listing fits the same truck.

The Adjustable Series uses the same fuel air separation design as the Titanium Signature Series, fitted with an adjustable fuel pressure regulator. Instead of living with whatever spring FASS shipped, you set outlet pressure to suit the truck. A stock truck, a mild tune and a competition build don't all want the same supply pressure.

Per FASS, 100 GPH covers stock to 600 HP. If you're building past that, call us and we'll talk through a bigger system.

Why we like it

• The adjustable regulator lets you dial pressure for the build (per FASS)
• Same fuel air separation design as the Signature Series (per FASS)
• Water separation and filtration built into the unit
