FAQ
What’s the adjustment range?The regulator can be adjusted up to roughly 0–100 PSI depending on your system setup.
What does the boost compensation port do?
It references intake manifold pressure so fuel pressure can rise under acceleration to maintain delivery on high-demand pulls.
Do I need a separate gauge?
The body includes a dedicated gauge port so you can monitor and set pressure quickly with your preferred fuel pressure gauge.
Will this work with my FASS Titanium Signature system?
Yes—it's a universal adjustable regulator and pairs well with FASS Titanium Signature systems on higher-horsepower builds. Use the current XWS/PF filter pairs noted above.
