The fuel pressure regulator is a device that is designed to maintain pressure in the injectors at different operating intensities. In fact, this regulator is a diaphragm valve, which is pressurized by fuel on one side and by the spring of the intake manifold on the other. The regulator is located on the fuel ramp, and the principle of its operation includes the following points: at the initial stage of pump operation, the fuel mixture leaves the tank and is cleaned in the filter; then it enters the regulator, where the system constantly maintains its homogeneous pressure. The supply includes fuel pressure regulator, hoses and all necessary accessories. Please note: professional installation is recommended.
