Have a aux.fuel tank from Downey. It mounts above the spare tire. Holds about 14 gal. fits 79/88 trucks Gravity feeds into your stock tank. These sell for about $450 will sell mine for$250. No dents or rust. Would prob. be about $25/$30 to ship west of Rockies. Shipped from Moab Utah 84532 Can see a picture on Downey's webb site. Because of so many dead beat buyers who say they want stuff and you never here from them the way I do this is you post on the thread you want it and have sent the $$. I 'll want a $50 nonrefundable deposit. Then after I recieve your deposit I will box and weigh to, give you the total due. Have a good ref. from Yota tech.com sale last week. I also amended the years it fits . I thought it stopped @ 85 but cat. says it fits 88 trucks.
