Abstract:
A fuel pressure regulator and fuel filter module for filtering and controlling the pressure of fuel delivered from a fuel pump within a fuel tank to an engine comprising:a one-piece body having a radially extending flange constructed to be sealed to the fuel tank;a depending annular skirt integral with the body at one end and open at its other end;an annular fuel filter received in the skirt and having a generally cylindrical wall defining an open interior of the filter;a fuel supply passage formed in the body and having an inlet in communication with the fuel pump and an outlet in communication with the fuel filter, a fuel outlet passage formed in the body and having an inlet communicating with the fuel filter and an outlet adapted to communicate with the interior of the filter and with a fuel line through which fuel is delivered to the engine, the fuel filter being disposed between the supply passage and the outlet passage;a fuel pressure regulator having an inlet in communication with the fuel outlet passage and a bypass outlet which fuel delivered from the fuel pump in excess of the engine's fuel demand is returned to the fuel tank whereby fuel is supplied under pressure from the fuel pump to the fuel supply passage whereupon the fuel flows through the fuel filter and is communicated with the fuel outlet passage and with the inlet of the fuel pressure regulator which discharges excess fuel into the fuel tank through the bypass outlet corresponding to the engine's fuel demand and the one-piece body substantially prevents the escape of fuel vapors to the atmosphere through the module.
