Replaces rusted or damaged gas tank perfectly. Rust resistant (heavy-gauge steel is plated inside and out) and strong (electrically welded seams are reinforced; each tank is pressure tested for leaks). Installs using existing original sending unit, filler neck and hardware (depending on application). Always replace rusted straps; new straps sold in pairs. Limited 3-year warranty. New sending units, filler necks and straps sold separately.
