Fuel filter with Fuel Pressure Regulator, MPI, Assembly Overview

In fuel systems without return flow for vehicles with MPI engine, the fuel pressure regulator is positioned in the fuel filter. In this system, only the fuel
supply line is routed forward to the engine compartment. Excess fuel is routed into a return line from the fuel filter and back into the fuel tank.
