Abstract

Method and system for metering a supply of a fuel into a high pressure fuel pump (24). The method varies the pressure of the fuel supply going to the high pressure fuel pump (24). The system uses a control valve (14) disposed in the inlet line (12) in parallel with the high pressure fuel to vary the pressure of the fuel supply going to the high pressure fuel pump (24).
