PrevThe fuel pressure regulator is located on the supply side of the fuel system, immediately upstream of the carburetor or downstream of the fuel injectors. Stock/OEM regulators often have a fixed pressure setting, while most aftermarket regulators are adjustable by design. Adjustable regulators allow the user to set the fuel pressure based on their unique combination of components and application.
Pressure regulators also provide the benefit of consistent fuel pressure under severe load and/or RPM. Under wide-open-throttle situations, the engine requires more fuel than it does at idle. Some regulators use a vacuum signal to "see" this additional load and provide the proper ratio needed for the conditions. This is even more important on boosted or nitrous engines that need additional fuel volume to minimize the chance of detonation. No matter which fuel pump you choose, know that all electric fuel pumps will require a regulator, while most mechanical fuel pumps won’t require a regulator.
