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 regulatorÕs 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 systemÕs ability to cope with minor power modifications.
