Abstract: A fuel filter and pressure regulator assembly includes a housing, an inlet tube, an outlet and return tube each made of stainless steel. An annular filter element is disposed within the housing and abuts at one end a pressure regulator element which is mounted within an O-ring retainer that is fixed within the housing. A resilient device, such as a wave washer or O-ring, is compressed as the assembly is assembled. In operation, fuel flows in through the inlet tube which is radially offset at a first end of the housing and into an annular space around the annular filter element. The fuel then flows through the filter media and the filter element and out of the outlet tube which is aligned with a hollow core of the filter media. If fuel pressure is too high, the fuel then flows through the pressure regulator, out of the return tube and back to the fuel tank.

Abstract: A quick connect fluid coupling is disclosed for use with a fuel tank having an opening. The coupling includes a coupling body having a tubular retainer housing and a tubular fill tube which is telescopically positioned through the retainer housing. The retainer housing also includes an outwardly extending flange which abuts against the outer surface of the tank around the tank opening. The fill tube is telescopically received within the retainer housing and is movable between a locked position and an unlocked position with respect to the retainer housing. The fill tube is also smaller in cross sectional shape than the tank opening so that the fill tube can be positioned through the tank opening and within the interior of the tank.

Abstract: A novel fuel tank is disclosed for a vehicle. The fuel tank includes a first and second housing part, each having an outer peripheral flange. The flanges are adapted to abut against each other and, in doing so, form a chamber between the central portions of the housing parts. These flanges are then sealingly secured together. Each housing part is a laminate structure having an outer layer constructed of an abrasion and impact resistant material, a vapor barrier layer constructed of a material impervious to hydrocarbon vapors, and a chemically resistant layer constructed of a material resistant to erosion from hydrocarbons and conventional fuel additives. Each housing part may also have additional layers, such as a heat and light reflective layer adjacent the outermost abrasion resistant layer, as well as a structural layer to add strength and rigidity to the overall tank.
