Abstract
A fuel filter comprises a filter head having an inlet and an outlet. A filter element is connectable to a nipple portion in the filter head. An actuating projection supported by the element is engageable with a valve element in the nipple portion to open flow through the nipple portion when the filter element is attached to the filter head. The filter head includes an annular threaded peripheral flange, and the element includes a corresponding annular threaded peripheral flange which together cooperate to secure the element to the head. A manual priming pump in the filter head includes a pair of check valves to control the flow of fluid through the head when priming the filter. A heater assembly includes a heater pan which encloses the heater elements and also includes the nipple portion, formed unitary therewith.
