ABSTRACT:
A device that is adapted to be mounted to an interior surface of a polymeric fuel tank includes a body, a weld foot adapted to be inserted into the molten inner surface of the fuel tank and having a support surface adapted to control insertion of the weld foot into the molten inner surface of the fuel tank and to position the device relative to the inner surface, and a break zone positioned between and interconnecting the weld foot and the body and having a structural cross section that is weaker than the weld foot and the body such that under sufficient force, the break zone will fracture and allow the body to separate from the inner surface of the fuel tank, thereby leaving the weld foot embedded within the inner surface of the fuel tank.
