ABSTRACT:
A control system for a fuel delivery system regulates fuel pressure on the filtered side of a fuel filter and relieves excessive primary pump flow from the unfiltered side of the filter. The valve also selectively provides warm fuel to de-wax the fuel filter after a cold start. Once wax build-up is no longer an issue, the warm fuel is directed to a fuel cooler or a heat sink, such as the fuel tank. The control system prioritizes the maintenance of filtered fuel pressure over maximizing fuel returned for cooling. Also, the fuel filter is protected from excessive fuel pressure differential.
