ABSTRACT:
A mounting system for electric pumps used in automotive vehicles, especially those in which the pump is installed in the fuel tank. To reduce pump and pump motor vibrations and noise, which may be objectionable to passengers, the pump is mounted within a jacket enclosure carried in the vehicle fuel tank. A suspension for the pump within the jacket consists of identical mount rings of relatively soft flexible material which has internal and external relatively thin projections to contact the inner walls of the jacket on the outside of the ring and to contact the pump housing on the inside of the ring. Radial continuations of the projections establish the axial location of the pump within the jackets.
