Abstract
A method of pressuring fuel for a direct injection fuel system via a fuel pump in an engine is provided. The method includes, during a first mode, adjusting a magnetic solenoid valve (MSV) to control pump outlet pressure and during a second mode, deactivating the MSV and controlling pump outlet pressure via a noise-reducing valve assembly on an inlet side of the fuel pump.
