Where should I mount my fuel pressure regulator?
In many cases, you can mount the regulator in a location to satisfy ease of installation, adjustment, and appearance. However, in the cases of high power applications, extra low fuel pressure systems, and high-g launches, it’s best to mount the regulator as close to the fuel delivery destination as possible.
What happens when the fuel pressure regulator goes bad?
A faulty fuel pressure regulator may cause the vehicle to experience misfires, a reduction in power and acceleration, and a drop in fuel efficiency. These symptoms can also be caused by a wide variety of other issues so having the vehicle properly diagnosed is highly recommended.
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.

Will a car run with a bad fuel pressure regulator?
A bad fuel pressure regulator can create a difficult to start or ‘no start’ engine. If the ECU can’t measure the excess fuel coming through the fuel pressure regulator vacuum line, it will usually cause the engine to run rich (too much fuel). When the engine is hot, this can make it harder to start the engine.
Can you fix a fuel pressure regulator?

How important is a fuel pressure regulator?
A fuel pressure regulator helps maintain the fuel pressure in the Electronic Fuel Injection System. If the system needs more fuel pressure, the fuel pressure regulator allows more fuel to go to the engine. This is important because that is how the fuel gets to the injectors.
Is higher fuel pressure better?
Remember, as fuel pressure is raised higher and higher, the flow available from the fuel pump gets smaller and smaller.
