Turbosmart's FPR800 is a motorsport-proven fuel pressure regulator that supports up to 800HP fuel systems. With a Stainless Steel valve and seat, MILSPEC diaphragm and industry-leading 1:1 fuel ratio control, there's no application too harsh for the FPR800. Available in Black, Blue, Red and Purple, the FPR800 is easily at home in a race application or modified street car.
Featuring two 1/8' NPT inlet ports, one 1/8' NPT return port and 1/8' gauge port, 30-90 PSI base pressure adjustment, 1:1 ratio, premium MILSPEC diaphragm and stainless steel valve + seat allow for ANY fuel type including E85 and is suitable for engines with up to 800hp fuel systems. Turbosmart FPRs feature a non-directional bias to regulation, so no matter where the fuel comes in, they will regulate the same.

Why buy a Turbosmart Fuel Pressure Regulator?
All Turbosmart FPRs are CNC machined in-house from billet aluminium + stainless steel and hand-assembled and tested to ensure maximum precision. Turbosmart FPRs have been designed to provide smooth and stable fuel pressure delivery under all conditions, from idle to full throttle. They are suitable for use with electric and mechanical fuel pumps. The FPR range features an easy screw and lock adjustment and provides a stable 1:1 ratio between fuel and manifold pressure. Each FPR is backed by various accessories such as fuel rail adapters, gauges and fittings to suit the most popular makes and models.
What is a Fuel Pressure Regulator?
A fuel pressure regulator must maintain constant fuel pressure above the intake manifold pressure. Most commonly fitted to the Fuel rail as injectors require a more significant feed pressure than inlet manifold pressure to provide adequate fuel spray for fuel-injected vehicles.
When do I need to Install one? Or upgrade my factory one?
Installing performance fuel injectors or high-flow fuel pumps requires an aftermarket fuel pressure regulator to allow pressure adjustments while maintaining a stable base pressure. They can also maximise a standard fuel system's ability to cope with minor power modifications.
What does FPR800 or 1200 mean?
A Fuel Pressure Regulator's capacity has been tested when you need to bypass fuel back to the tank rather than use it. A Fuel Pressure Regulator's capacity has been tested when you need to bypass fuel back to the tank rather than use it. Turbosmart Fuel Pressure Regulators are not rated for your target engine horsepower - Rather, they are rated based on your fuel system capability. So it's not how much HP your engine makes - IT's how much supply your pump & fuel system has that could need to be returned to the tank under situations likes declaration or at idle.
Will Turbosmart FPR work on a Semi Dead-Head System?
Yes. The Turbosmart FPR range is a regulator, and it doesn't matter where you fit it; it will accurately regulate the pressure of the fuel circuit, no matter where on the car you have installed it.
Can These handle Race Fuel?
Yes. With Turbosmart's Unique Diaphragm, stainless salve and seat, we've designed, proven and validated these regulators with the harshest types of fuels around, including Methanol, Lead Race Fuel and E85.
