Abstract
A filter system is disclosed which comprises a housing having a first inlet and a first outlet. A filter element is located between the first inlet and the first outlet. A temperature sensitive valve controls communication between a first inlet side of the filter element communicating with the first inlet and a return line from a fuel pump so that when the fuel temperature is low, hot fuel returning from the pump is supplied to the first inlet side of the filter element. When the fuel temperature increases, the returned fuel is returned to the fuel reservoir rather than to the first side of the filter element.
