A tank filling and pressure relief assembly. A cover member has a seat for sealingly closing the tank opening. A stem is attached at one end to a piston in a cylinder (which is attached to the cover member and extends downwardly therefrom into the tank) and at the other end to a strongback. The strongback is pivotly mounted to swing the assembly away from the opening for filling thereof and to swing the assembly back into position to seat the cover member and is lockable in a position to lockingly urge the cover member to the closed position. The stem is flexibly coupled to the strongback to evenly distribute the seating force so that binding does not occur and is threadedly attached thereto so that the set pressure for pressure relief may be adjusted by access to the stem for turning thereof through an opening or cut-out in the strongback.
