ABSTRACT:
An in-tank fuel module adapted to be mounted within a fuel tank of predetermined vertical dimension through a circular opening in an upper wall of the tank. The module includes a canister having a one-piece hollow cylindrical external wall of blow-molded plastic construction and of diameter to fit through the tank wall opening. Circumferential convolutions that extend around the wall form axially resilient bellows in the canister wall, and a fuel inlet is disposed at the lower portion of the canister. A cover is fastened to the upper edge of the canister, and is dimension to close the opening in the tank top wall with the canister extending vertically through the tank. The canister is axially dimensioned with respect to the vertical dimension of the tank so that the bellows in the canister sidewall are axially compressed and resiliently hold the lower portion of the canister against the bottom wall of the tank. A fuel pump is mounted within the canister and provides fuel under pressure through a fuel line that extends through the module cover.
