Abstract

A priming pump valve for use in conjunction with a fuel system, such as a diesel engine, that does not result in a lag in the fuel flow during normal system operation. The priming pump valve has a control valve movable between a first position for normal operation and a second position for priming that allows for efficient priming of the fuel system when in the priming mode and unrestricted flow of fuel during normal operation of the engine.
