Abstract
A fuel tank assembly (12) is provided for containing liquid fuel and supplying that fuel, upon demand, to an internal combustion engine. The assembly (12) includes a tank (14) in which is disposed a fuel pump module (18). The fuel pump module (18) includes a cup-like reservoir (34) which houses a fuel pump (46) and carries along its outer side wall (36) a fuel level sender unit (32). A float arm (60) extends pivotally from the fuel level sender (32) and swings up and down as the level of fuel in the tank (14) changes. The float arm (60) is pivotally supported on a carrier (58) attached to the side wall (36) of the reservoir (34). A sliding interface (62) is disposed along the side wall (36) of the reservoir (34) for slidably receiving and securing the carrier (58) along a captured alignment path. The fuel level sender (32) can be infinitely positioned in the longitudinal direction along the sliding interface (62) during assembly of the fuel pump module (18). The sliding interface (62) provides a more robust, more adaptable technique for positioning and fastening the fuel level sender (32) upon the reservoir (34).
