<p>A canister (22) with an electric fuel pump therein is connected to a cover (46) for an access port (18) through which the canister (22) is installed on a fuel tank (10) of an automobile by three hollow struts (76A,76B,76C). Each strut (76A,76B,76C) has a first end (78) press-fitted into a socket (70) on the cover (46) and is telescopically received in a respective bore (82) in the canister (22). Coil springs (88A,88B,88C) around each strut (76A,76B,76C) urge relative separation between the strut (76A,76B,76C) and the cover (46) and a flare at a second end (80) of each strut (76A,76B,76C) defines a stop to limit said relative separation. A passage (74) in the cover (46) from a return fuel connection (60) on an exposed side of the cover (46) to one of the sockets (70) conducts low-pressure return fuel to the hollow strut (76A) press-fitted therein. The return fuel flows back to the canister (22) through that hollow strut (76A).</p> |
