Fuel Pressure Regulators

Fuel injection is a complex mechanical process and includes many systems working in concert to maintain constant pressure levels and quick response to fuel demands. One important aspect of fuel injection is pressure regulation. Fuel pressure regulators help maintain fluid volume moving against a restriction in order keep fuel from flowing back into the fuel tank. A fuel pressure regulator restricts fuel from returning to the tank in calibrated amounts, thereby enhancing fuel pressure and overall engine performance.

Styles of Fuel Pressure Regulation

Early fuel pressure regulation systems consisted of a slide valve, known as a push valve, which was an internal part for fuel distributors. Adding or removing shims from the slide valve and, as a result, regulating flow to the desired level, regulates pressure in these systems. Conventional diaphragm style fuel pressure regulators that meet the higher fuel demands of today's high performance automobiles have replaced push valves.

On the cutting edge of today's racing technology are fuel pressure control units. These dynamic systems include features such as dual porting and are highly responsive to changes in fuel demands such as launch, gear change, and nitrous oxide actuation. Built to handle high performance gasoline, alcohol, and nitrous systems, fuel pressure control units are the new wave of fuel pressure regulation. Fuel pressure control units are currently available for any carbureted unit. Any racing need can be met, whether on the street, the track, mud bogging, or powerboat racing.

Another high performance option for fuel pressure regulation are fuel injected pressure control units. These high performance units offer precision flow control--a huge advantage over older style ball-over-hole units. These units are customizable to any engine, and specific spring combinations can be suited to fit any fuel flow situation at the desired pressure specification.
