Abstract
A diesel engine fuel system of the type which includes a fuel heater upstream of a filter in the fuel feed line from the tank to the engine injector and wherein a diverter line is connected at one end in the engine-to-tank return line and at its other end to the feed line downstream of the filter. A valve controls flow in the diverter line and is adapted to permit flow therein while substantially stopping return flow to the tank only when the heater is operating. The result is a dramatic improvement in heater efficacy.
