ABSTRACT:
A fuel system for an internal combustion engine is disclosed having a fuel distributor to which one or more injectors are operably connected for injecting fuel into the intake manifold of the engine. A valve assembly in the system has a valve which is disposed for movement between a first position in which fuel is recirculated through the distributor for return to the fuel supply, and a second position in which fuel supplied to the distributor is not recirculated to the supply thereby eliminating returned fuel as a heat source for said fuel supply when the valve is in the second position.
