ABSTRACT:
A level detecting assembly that features a level detecting device which includes a float hinged by an arm for displacement in accordance with a level of fuel in a plastic fuel tank. The level detecting device also includes a reference rod extending from a holder positioned in the plastic fuel tank. The tank is supported by a band on a motor vehicle. The lower end of the reference rod abuts the inside wall of the tank at or in the vicinity of the band, so that deformation of the tank is prevented, and precise level detection is achieved. Also, an elastic member is provided at the end of the reference rod. The elastic member is dimensioned and arranged for preventing the downwardly biased reference rod from damaging the inside of the tank bottom. The assembly also features an outer skin preferably formed of an elastic material positioned between the band or bands and the tank.
