Fuel Pressure Regulator: Description and Operation
The fuel pressure regulator maintains a constant fuel pressure to the fuel injectors. When the difference between the fuel pressure and manifold
pressure exceeds 300 kPa (3.0 kg/cm2, 43 psi), the diaphragm is pushed upward, and the excess fuel is fed back into the fuel tank through the
return line.
