Rust Inside of Gas Tank

ROSchell · Aug 23, 2014

Hi,
I'm wondering if anyone can give me any tips on which product to use on the inside of the gas tank on my 1938 'D' John Deere to adhere the specs of rust to the tank so they don't plug up the carb. It got so each time I started the tractor, it ran a little worse. It would spit and pop until finally it wouldn't start at all. I noticed the sediment bowl had quite a bit of crud in it and I cleaned the tank as best I could, but there is still some fine crud in there that I can't get out. I want to get this completed so I can see if this was my problem or if I need some magneto work. Any advise at all will be appreciated. Thanks.

take off the tank ..put a lenth of chain or two in there tie then ends to a stik outside tank ,, strap tank to a tracter tire ,put the tracter in low gear , and shake rattle and roll that crud loose in the tank for 30 minutes,,mite add some aff or liquid wrench = , wash that crud out real good ,, you can use red kote when dry ,, I hang a lite bulb in the tank to aid drying ..lots of info on this subject in archives

Sounds like you want to avoid removing the tank. I have had very good luck siphoning dirt/rust /corruption from tanks. I use one of those $2.99 transfer siphons that you get at the hardware. It enables you to steer the end around. Of course use all possible safety measures.

I do have the tank off, and I have cleaned it out, but I can't seem to get everything out of there. One reason is there is a collar on the inside of the tank filler and it has a lip that extends into the tank, so when I drain the tank, not everything can run out of the fill hole. That's why I'm wondering about products that will line the inside of the tank and adhere the crud in there so it won't be a problem. Thanks for the responses so far.

There are a lot of references to Kreme and Red coat and there is also every now and then one about someone getting an old tractor that has the tank and line and carb all plugged up with pieces of a disintegrating liner. A siphon would be just the ticket for cleaning out around that ring.

Take your fuel tank to a radiator shop that will clean it in an acid tank. Then use the pour in liner. If you don't get it clean first and then put liner in, the liner will come loose and you will really have problems!

Like MR hikemper said just strap it to a lawn mower tire in low gear and have a beer or 2. I found nuts bolts and washers work the best. If there are no baffles to worry about some play sand works nice.

Have you been using ethanol gas? If so, that is the usual problem with these old tractors plugging their fuel systems.

Need to use non-ethanol (oxygenated) gas.

The vac I bought had a rusty tank...I strapped it to the rear tire of my ford 1600 . Still had lots of rust . I took it to the radiator shop .they dunked it a few times till the inside was clean. They found a few pin holes.. they are fixing the holes, then using red-kote. Hopefully this will do it.... I had the case 930 tank cleaned at the radiator shop, but I didnt seal it ... Ive had trouble with it clogging up.... Good luck
