Most autos now have an Digital returnless fuel offer method which includes no fuel stress regulator. Tension is controlled by a fuel pump driver module (FPDM) or simply a fuel pump Management module (FPCM) in reaction to commands with the PCM. On these methods, fuel force is managed by managing the speed with the fuel pump.
