Abstract
A securing apparatus is proposed for electric fuel pumps intended for direct in-tank installation, which enables satisfactory removal of fuel vapor from the suction area of the pump, but prevents the transmission of vibration onto the fuel spinner fixedly mounted in the tank. This is accomplished in that the elastic properties of one or more rubber elements, directly connected in the form of sleeves to the pump, are maintained even with the effects of aging, since the rubber elements are primarily stressed only by shear or bending forces. The pump is inserted, with the mounted rubber element, into a corresponding device in the fuel spinner and, so far as this is necessary, secured with clamping elements. The rubber elements fulfill the functions of holding the pump, sealing the pump suction chamber from the tank, damping noise, and removing vapor in the tank.
