Most autos now have an Digital returnless fuel offer technique that has no fuel pressure regulator. Stress is controlled by a fuel pump driver module (FPDM) or possibly a fuel pump Management module (FPCM) in response to commands through the PCM. On these programs, fuel force is managed by controlling the pace in the fuel pump.
