h67st Posted January 7 Share Posted January 7 The tank on my Brockway has a little rust in the bottom, and I've seen companies like POR15 that sell treatment for that. Has anyone used these treatments, and how did you like them? I'll steam it out real well before I use anything.

1961H67 Posted January 7 Share Posted January 7 I have used it on a small gas tank ( old farm tractor) i steam it really well, I can’t remember the name of what I used, but after I poured it in I had the advantage of rolling and turning the tank so it kinda coated the inside, it worked good for that, I don’t see why it wouldn’t work on Diesel also. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73732-fuel-tank-rust-repair/#findComment-544719 Share on other sites More sharing options...
70mackMB Posted January 7 Share Posted January 7 Saw a video some time ago of cleaning a fuel tank. They mounted it to a home owners size electric cement mixer to spin it. Don't remember what they used inside to clean and seal it. .....Hippy This is not the video l was thinking of but you get the idea.

hicrop10 Posted January 7 Share Posted January 7 I have todo this on the tanks for my b87, problem being is the weight.I’m thinking of putting tank on work bench and just shaking it the best I can and doing some spinning.

Joey Mack Posted January 7 Share Posted January 7 Yep,, If I do my generator tank, I bet I will have to tie my el-cheapo mixer down, or maybe put my fork lift forks down on the legs, to keep it from flipping over.

Popular Post hicrop10 Posted January 7 Popular Post Share Posted January 7 First I’ve made up a fuel cap so I can put some pressure say about 5-8lbs of air and see if there’s and small pin holes. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/73732-fuel-tank-rust-repair/#findComment-544731 Share on other sites More sharing options...
mrsmackpaul Posted January 7 Share Posted January 7 Remember if you blokes are gunna cut into a diesel tank to clean them out to fully wash it out with petrol first Diesel seeps into the seams and steel and evaporates out as it gets heat from cutting and welding etc This makes the tank full of fumes and explosive again Dangle a air hose in running freely to force any fumes out But wash out with petrol first is a must But you all aren't talking about cutting a hole to clean a tank out so disregard my comments, my comment is just encase you decide to fairly get stuck in Happy days everyone Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73732-fuel-tank-rust-repair/#findComment-544778 Share on other sites More sharing options...
Popular Post 1961H67 Posted January 8 Popular Post Share Posted January 8 Hopefully you won’t have to go down this road, mine had about 3 pin holes on each side, I was afraid it was too thin for tank sealer, it came out pretty good, a lot of welding, grinding, I had another tank,, same condition. 5 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73732-fuel-tank-rust-repair/#findComment-544785 Share on other sites More sharing options...

1961H67 Posted January 8 Share Posted January 8 If the tank was just rusty and no pinholes I would try the sealer , if they were taken off the truck and steamed out good, then you could pour the sealer in and roll it around, hopefully using a flashlight to make sure the sealer oozed around and covered the rust,, Thank you, it as a lot of work, I filled it with water and did have a couple leaks on the welds , grind and reweld a few times, it’s got about 1/2 tank of fuel and I haven’t seen any leaks. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73732-fuel-tank-rust-repair/#findComment-544794 Share on other sites More sharing options...
Popular Post mechohaulic Posted January 8 Popular Post Share Posted January 8 this will be a redneck thought ;; instead of a cement mixer for large tanks ; with all the safety procedures followed is it possible to use a big truck with one set wheels jacked up . having tank VERY securely to tires and slowly spin ?? would be easier to strap tank to set of tires and doubt the truck will tip over.. even if you spin it by hand ??? 3 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73732-fuel-tank-rust-repair/#findComment-544795 Share on other sites More sharing options...
BOBWhite Posted January 8 Share Posted January 8 I've seen people strap tanks to tractor tires and spin them around all day that way. As for safety filing it up with water can work, and I've heard of people piping exhaust gasses into the tank. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/73732-fuel-tank-rust-repair/#findComment-544798 Share on other sites More sharing options...
mrsmackpaul Posted January 8 Share Posted January 8 I can't see why not It should work, just have it ticking over nice and gentle, wouldn't leave it on there for hours on end but I reckon if it works then why not I guess if it had a limited slip diff and abs brakes or traction control it might be different Paul 2 Quote Link to comment https://www.bigmacktrucks.com/topic/73732-fuel-tank-rust-repair/#findComment-544799 Share on other sites More sharing options...

And that's not a complete belly replacement like 1961H67 did.

mowerman Posted January 8 Share Posted January 8 Yes, I was kind of curious about that because I have one Theo was just going to have shortened, but I just decided to reroute the exhaust around it instead because I figured it would probably be at least three or 400 for that price of just another tank. Thanks for that….bob Quote Link to comment https://www.bigmacktrucks.com/topic/73732-fuel-tank-rust-repair/#findComment-544810 Share on other sites More sharing options...
1961H67 Posted January 9 Share Posted January 9 Hopefully you can steam it out and just seal them , a few quarts of that POR15 would be much cheaper than all that cutting and welding. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73732-fuel-tank-rust-repair/#findComment-544828 Share on other sites More sharing options...
