What Is A Fuel Pressure Regulator

Your fuel pressure is regulated by… you guessed it, the fuel pressure regulator. This regulator maintains optimal pressure in your engine and injectors, sending excess back towards the gas tank. A faulty regulator is awful because it can lead to overflows, causing leaks or even a fire in the worst case scenario.
