Fuel Pressure Regulator: Description and Operation
PURPOSE AND OPERATION
The Fuel Pressure Regulator is a mechanical device controlled by plenum chamber vacuum. It ensures that fuel rail pressure is maintained at a
constant pressure difference of 2.5 bar (36.25 psi) above that of the manifold.
When pressure exceeds the regulator setting, excess fuel is returned to the fuel tank.
