ABSTRACT:
A fuel system for an automotive vehicle equipped with a diesel engine includes a fuel tank, a fuel injection pump, a fuel supply passage for conducting fuel from the fuel tank to the fuel injection pump, and a fuel return passage for conducting fuel from the fuel injection pump to the fuel tank. A hydraulically powered lift pump moves fuel from the fuel tank to the fuel injection pump through a fuel supply passage. The lift pump includes a hydraulic motor powered by fuel flowing through the fuel return passage and a primary fuel pump coupled to and powered by the hydraulic motor, with the primary fuel pump providing fuel to the injection pump through the fuel supply passage.
