ABSTRACT:
A diesel engine system in which fuel in a fuel tank having an air space above a fuel level is pumped to a fuel injection system disposed in spaced relation above the fuel tank, and excess fuel is returned to the fuel tank air space via an uninterrupted fluid flow path between the injection system and the air space of the fuel tank. The fluid flow path has a cross sectional area selected such that air from the fuel tank air space flows counter to fuel returning to the fuel tank by gravity during non-operation of the diesel engine, to maintain the space vacated by returning fuel near atmospheric pressure. A method embodiment includes the steps of providing an uninterrupted fluid flow return path between the injection system and the air space of the fuel tank, and sizing the fluid flow return path such that, during non-operation of the diesel engine, air from the fuel tank air space flows counter to fuel returning to the fuel tank by gravity, to maintain the space vacated by returning fuel near atmospheric pressure.
