WHY BUY A TURBOSMART FPR?
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 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 regulators job is to maintain constant fuel pressure above the intake manifold pressure.

WHEN DO YOU NEED TO INSTALL 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 systems ability to cope with minor power modifications.

Ideal for ANY fuel type including E85 and is suitable for engines with up to 800hp fuel systems.
