  • Patent number: 5142908
    Abstract: An assembly for mounting a fuel level sensing apparatus within a fuel tank of a vehicle includes a base member, a head member, and an elongated tubular member welded at one end to the base member and welded at the other end to the head member. The mounting assembly is positioned within a fuel tank and the head member is welded to a wall portion of the fuel tank. A fuel level sensing apparatus, having a guide portion and a mounting portion, is positioned within the mounting assembly, with the guide portion within the confines of the base member and the mounting portion releasably secured to the head member. A groove in the wall of the guide portion accommodates a rubber cushioning ring which is slightly compressed between the base member and the guide portion groove. Vehicle shocks and vibrations which would normally be transmitted to the fuel level sensing apparatus are dampened by the rubber cushioning ring.
