Fuel Pressure Regulator: Description and Operation
Description
The fuel pressure regulator maintains a constant fuel pressure to the injectors. When the difference between the fuel pressure and manifold pressure
exceeds 294 kPa (3.0 kgf/sq.cm, 43 psi), the diaphragm is pushed upward, and the excess fuel is fed back into the fuel tank through the return line.
