Function of the fuel pressure regulator
The electric fuel pump in the tank provides the required pressure in a car's fuel system. It can generate higher than necessary pressure, which can damage connections or lines and distribute fuel. Contact with hot components could result in a fire hazard.
To avoid this, a gasoline pressure regulator is used. The required pressure depends on the specific vehicle and engine and varies between 3 and 5 bar, according to the respective engine and load conditions. It is essential to ensure the optimum pressure for each situation.
