Just throwing this out there if anyone is searching for a fuel tank for their 1980 Pickups and can't find a replacement. The later model '84-88 Pickups carbureted 17 gallon gas tanks will fit the 1980 Pickups with the long bed. I have confirmed it with my 1980 Pickup with the long bed and 20R engine. A direct fitment at that! JC Whitney #REPT670106 https://www.carparts.com/fuel-tank/jc-whitney/rept670106
