This is where the fuel pressure regulator is doing its job, to adapt the fuel supply to the fuel demand. To accommodate for a successful fuel and air mixture, a proper fuel pressure is required in all situations, both at low revs and high revs, regardless of the power output.
On the other hand, blocking the pass-through to the fuel tank off completely, the fuel pump will try to force too much fuel into the injectors which will cause them to fail. The Fuel Pressure Regulator is a must have item for any EFI system, without it, the fuel rail will not be able to build up enough pressure to support the injectors with the sufficient amount of fuel, the fuel will instead flow straight through and not reach the injectors. What is the purpose of a Fuel Pressure Regulator? We choose to make our own guide, with sleek and easy-to-understand graphics to fill up the gap. Many of the available online guides online are outdated, describing older designs and many times they do not apply to modern injection systems. Here we will go through the basics, how it works, how it functions in a fuel system and explain the different parts. We often get questions about our Fuel Pressure Regulator, how it works, what role it plays in a fuel system and what it is that makes us promise that it is suitable for even over 1000 HP.
