eddeere Posted August 30, 2015 Share Posted August 30, 2015 Since I have the tanks off my B model I would try to get small amount of rust off the inside. I have read some use muriatic acid other say not to use it can cause flash rust after neutralizing. Thought about using Ospho but have read it may leave a zinc residue. Any advice would be appreciated. Quote Link to comment https://www.bigmacktrucks.com/topic/41569-removing-rust-from-tanks/ Share on other sites More sharing options...

eddeere Posted September 1, 2015 Author Share Posted September 1, 2015 Relining is the way to go. But I want to remove the rust first. Quote Link to comment https://www.bigmacktrucks.com/topic/41569-removing-rust-from-tanks/#findComment-302244 Share on other sites More sharing options...

Maddog13407 Posted September 2, 2015 Share Posted September 2, 2015 I have ground down the welds, cut the end caps off many B model tanks, sandblasted them and coated them with Red Kote lining and welded the end caps back on then air tested. not hard just time consuming Quote Link to comment https://www.bigmacktrucks.com/topic/41569-removing-rust-from-tanks/#findComment-302321 Share on other sites More sharing options...
eddeere Posted September 2, 2015 Author Share Posted September 2, 2015 Thanks all. I put in a couple of qts. of Murphys Soap Oil sloshed it around and let set then flushed out. this seemed to clean most of the crud out. There was not as much rust as I thought. Added a gallon of muriatic acid flushed out then neutralized with backing soda. By now the tanks look good inside. Called the maker of OSPHO. They said that people have used this for years for rust in fuel tanks with no complaints. I put in a gallon of OSPHO and let set sloshed around and let set overnight per their instructions. Drained and letting everything dry now. I am satisfied with what I see now.
