Description
Overview
The FASS Fuel Systems Adjustable Fuel Pressure Regulator (Part No. FPR1001) is a universal automotive fuel pressure regulator engineered for aftermarket performance applications that demand higher fuel pressures than a typical daily driver. Whether you’re building a drag race vehicle, a competition pulling truck, or a high performance marine setup, this fuel regulator gives you precise, adjustable control over the fuel delivered to your engine. Designed for both gas and diesel applications, it’s a versatile FASS solution for enthusiasts who need consistent pressure under heavy fuel demand.
Key Benefits
At the heart of this unit is fully adjustable fuel pressure, letting you dial in exactly what your combination requires. Unlike a fixed fuel pressure regulator, the FASS FPR1001 adapts to your build, making it a smart choice when you’re upgrading a system or performing a fuel pressure regulator replacement on a high-output truck or SUV. If you’ve been chasing symptoms of a bad fuel pressure regulator — inconsistent pressure, poor performance under load, or a struggling fuel curve — an adjustable, purpose-built regulator like this gives you the control to fix the problem the right way.
For added convenience, FASS pre-drilled and tapped a fuel pressure gauge port directly into the housing. This built-in port makes monitoring and adjusting your regulator simple, eliminating the guesswork that comes with trying to tune blind. As an added performance advantage, the regulator also features an engineered boost compensation port. By running a line from your intake manifold, the regulator can increase fuel pressure in step with boost — a major benefit during active acceleration when fuel demand spikes.
Highlights
- Adjustable fuel pressure for precise, application-specific tuning
- Compatible with both gas and diesel applications
- Built-in, pre-drilled and tapped fuel pressure gauge port for easy adjustment
- Boost compensation port to raise fuel pressure under acceleration
- Universal design suited to drag race, competition pulling, and marine builds
Fitment
This is a universal adjustable fuel pressure regulator designed to fit Truck/SUV performance applications. Because it’s built for aftermarket, high-pressure setups rather than stock daily-driver replacement, it’s ideal for enthusiasts assembling or upgrading a serious fuel system. It is sold as each (Part No. FPR1001).
When your build outgrows a stock fuel regulator, the FASS Adjustable Fuel Pressure Regulator delivers the adjustability, monitoring, and boost-referenced pressure control that performance and competition applications demand. Choose it to take command of your fuel curve and keep pressure right where you want it, from cruising to full-throttle demand.
