Where is a fuel pressure regulator located?
A fuel pressure regulator is located at the end of the fuel rail and it connects to the injectors of the car. To locate the fuel regulator, you must first find and follow the fuel rail in your engine and you can find it at the end, before the fuel gets into the engine. The location will depend on each type of car model and to determine the location you need to either follow the fuel rail around or locate the injectors directly if you can. It is usually attached to the fuel rail of the car so you can also check in that area of the engine as you try to find the fuel pressure regulator.
