Abstract
A canister with an electric fuel pump therein is connected to a cover for an access port through which the canister is installed on a fuel tank of an automobile by three hollow struts. Each strut has a first end press fitted into a socket on the cover and is telescopically received in a bore in the canister. Coil springs around each strut urge relative separation between the strut and the cover and a flare at a second end of each strut defines a stop to limit relative separation. A passage in the cover from a return fuel connection on an exposed side of the cover to one of the sockets conducts low pressure return fuel to the one of the hollow struts press fitted therein. The return fuel flows back to the canister through the one hollow strut.
