What is a Fuel Pressure Regulator?

A Fuel Pressure Regulator is an important mechanical device used in automobile engines and its purpose is to maintain regular fuel pressure at all driving conditions. Without a  Fuel P ressure R egulator, flow of fuel cannot be kept at normal level, especially after installing new fuel pumps. Fuel Pressure Regulators  are available in several sizes and shapes, and you need to buy the right model for your vehicle.

All vehicles come with a Fuel Pressure Regulator fitted as a factory standard part. However, a performance Fuel Pressure Regulator can also be installed to either replace the factory Fuel Pressure Regulator or work in conjunction with the factory Fuel Pressure Regulator.

How does a Fuel Pressure Regulator work?

The device is regulated by a spring based diaphragm and a valve. It has an inlet and outlet nipple as well as a fuel return line to redirect excess fuel back to the fuel tank.

An adjustable Fuel Pressure Regulator allows you to control the pressure (psi) levels by loosening or tightening a screw usually located at the top of the regulator. The screw then forces the spring diaphragm to change causing either increased or reduced fuel pressure (depending on whether it is tightened or loosened).

What are the benefits of having an adjustable performance Fuel Pressure Regulator?

Here are just a fuel reasons why you should purchase an adjustable performance Fuel Pressure Regulator:
  • Allows your vehicle to achieve optimal fuel pressure to maximise performance
  • Automatically responds to an increase in acceleration
  • Reduces damage to your engine resulting from poor fuel pressure
  • Better fuel economy.
  • Lower carbon monoxide emissions from your vehicle
  • Can either replace or work in conjunction with your existing regulator
