摘要： A fuel filter assembly having a pressure sending unit for filtering and monitoring fuel and fuel pressure for diesel engines and the like comprising a filter head, a spin-on element and collection bowl. The filter head is fastened to an engine or other suitable structure by flange, bolts and supports the fuel filter assembly by monitoring fuel pressure by utilizing a pressure sending unit in fluid communication with an outlet port on the filter head. Preferably, filter head is a die cast head and includes therein typical inlet port, outlet port, and connected respectively thereto, inlet chamber and outlet chamber. Filter head is a generally circular structure having a flat annular mounting surface. The filter head may further comprises vent ports, vacuum switch ports or both, which are in fluid communication with outlet ports and return check valve ports that are in fluid communication with inlet ports. Still further, filter head is in fluid communication with a pressure sending unit, which is in electrical communication with a pressure monitoring device or similar warning system.
