Do I need an aftermarket fuel pressure regulator?

Truth be told, aftermarket FPRs are not necessary and the factory OEM FPR will do the job just fine. Even installing a Walbro 255L/H fuel pump and/ or larger injectors does not require you to switch to an aftermarket FPR as the factory one will cope happily.

Is there a difference in fuel pressure regulators?

The difference is that an aftermarket, adjustable regulator has the ability to adjust when that diaphragm opens using preload on the system. The size of your fuel lines also is relevant to pressure, Mills explained. The smaller the fuel line, the more pressure drop you’ll have over a given length of line.

What are the symptoms of a fuel pressure regulator?

How do you adjust the fuel pressure regulator?

Using the adjustment on the fuel pressure regulator, set the fuel pressure to 36psi via the needle on your fuel pressure gauge. Turn off the ignition, remove jumper, reinstall the relay and cover, and start the car. The fuel pressure at idle should be LESS than 36psi. When you are in boost it will be MORE than 36psi.

How do you test a pressure regulator?

The easiest way to test fuel pressure regulators is with the use of a fuel pressure gauge. So, This test checks the operation of the fuel pressure regulator to make sure it changes line pressure in response to changes in engine vacuum.

What does a fuel bypass regulator do?

The bypass regulator opens up to allow excess fuel volume to return to the tank so as not to exceed the set pressure. As your nitrous and carb demand more fuel the bypass regulator will reduce the amount of bypass fuel going to the return line and more volume goes to the ‘load’ – providing that the pump produces more than…

What is an adjustable fuel regulator?

The adjustable fuel regulator is a component in the engine which helps in regulating fuel pressure and this is cycled throughout in the engine. Some regulators make use of vacuums. Any kind of potential issues is hence needed to be looked at as soon as it is detected so that complicated problems can be avoided.
