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 FPR’s have been designed to provide smooth and stable fuel pressure delivery under all conditions from idle to full throttle and are suitable for use with both electric and mechanical fuel pumps. The FPR range features an easy screw and lock adjustment and provide a stable 1:1 ratio between fuel pressure and manifold pressure. Each FPR is backed by a variety of accessories such as fuel rail adapters, gauges and fittings to suit most popular makes and models.

What is a Fuel Pressure Regulator?

A fuel pressure regulator’s job is to maintain constant fuel pressure above the intake manifold pressure. Most commonly fitted to the Fuel rail as injectors require a greater feed pressure than inlet manifold pressure, in order to provide adequate fuel spray for fuel injected vehicles.

When do I need to Install one? Or upgrade my factory one?

The installation of performance fuel injectors or a high-flow fuel pump requires the use of an aftermarket fuel pressure regulator to allow pressure adjustments while maintaining a stable base pressure. They can also be used to maximise a standard fuel system’s ability to cope with minor power modifications.

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.
