Abstract
An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.
Claims20
A fuel tank for an internal combustion engine comprising:
- a hollow body defining an internal reservoir configured for holding liquid fuel and a fuel fill opening configured for adding the fuel to the tank;
- a fuel pump assembly having a pump housing and a pump, the pump housing comprising:
- an upper housing unit coupled to the fuel fill opening;
- and
- a lower housing unit coupled to the upper housing unit, the lower housing unit receiving the pump within a longitudinal concavity.
A fuel pump assembly comprising:
- a pump housing comprising an upper housing unit and a vertically elongated lower housing unit coupled to the upper housing unit;
- the upper housing unit configured for coupling to a fuel fill opening in a fuel tank, the upper housing unit including an internal cavity;
- the lower housing unit in fluid communication with the internal cavity of the upper housing unit;
- and
- a fuel pump coupled to the lower housing unit;
- wherein the pump housing is configured to receive the fuel from a top opening of the upper housing unit and introduce the fuel into a reservoir of the tank in a lateral direction from the lower housing unit.
