Fuel Pressure Regulator mounts on the fuel rail of the multiport electronic fuel injection (EFI) system.
It holds a constant pressure difference between the fuel rail and the intake manifold by referencing manifold vacuum, keeping injector delivery consistent as engine load changes. Excess fuel is returned to the tank through the return line. Fitted to the V8 EFI petrol engine.
