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.

What is claimed is: 1. A method of attaching a device to the inner surface of a polymer fuel tank comprising: providing a device having a body and a weld foot adapted to be inserted into the inner surface of the fuel tank, the weld foot having a support surface adapted to control insertion of the weld foot into the inner surface of the fuel tank; heating the inner surface of the fuel tank to a molten state; inserting the weld foot into the molten inner surface of the fuel tank until the support surface contacts the inner surface of the fuel tank; allowing the weld foot to melt such that the weld foot and the inner surface of the fuel tank, molecularly interact; cooling the inner surface of the fuel tank and the weld foot to solid state, wherein the weld foot and the inner surface of the fuel tank are molecularly bonded together. 2. A method of attaching a device to the inner surface of a polymer fuel tank comprising: providing a device having a body and a weld foot adapted to be inserted into the inner surface of the fuel tank, the weld foot having a support surface adapted to control insertion of the weld foot into the inner surface of the fuel tank, the weld foot including a base having an axially facing surface defining the support surface, and a protrusion extending from the axially facing surface, heating the inner surface of the fuel tank to a molten state, inserting the weld foot into the molten inner surface of the fuel tank until the support surface contacts the inner surface of the fuel tank, and wherein inserting the weld foot into the molten inner surface of the fuel tank until the support surface of the base contacts the inner surface of the fuel tank includes inserting the protrusion into the molten inner surface of the fuel tank; allowing the weld foot to melt such that the weld foot and the inner surface of the fuel tank molecularly interact; cooling the inner surface of the fuel tank and the weld foot to solid state, wherein the weld foot and the inner surface of the fuel tank are molecularly bonded together. 3. The method of claim 2 including venting air from between the axially facing surface and the inner surface of the fuel tank as the protrusion is inserted within the inner surface of the fuel tank. 4. The method of claim 3 wherein said body further includes a break zone positioned between and interconnecting the weld foot and the body, the break zone 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 wall of the fuel tank, thereby leaving the weld foot imbedded within the inner wall of the fuel tank.
