Has anyone used electrolysis to remove rust from inside a gas tank?

Buddy · Jan 21, 2017

Yes. Have saved a few tanks. Only problem is, if there is a baffle in the tank. You need to be able to have site, of both sides with the electrolysis rod. The last tank I saved, and still use on the tractor today, is on one of my 8N Fords. It does work.

In order for it to work, you need line-of-site to the anode. That would be difficult inside of the tank.

I put the rod in the tank and prevented side contact with a cut off plastic water bottle. It worked very well for what I could see. The issue I had was afterwards the middle section where the two halves come together started leaking. That was not acceptable to me so I bought a tank off the internet. I don't regret that at all.

" if there is a baffle in the tank"

And 8N tanks have a baffle. How do you get the anode in there?

I did a few motorcycle tanks that way. Worked well. The last 2 tanks I've done I used that Evap-o-rust. It worked well too.

Good clean fuel is hard to beat.
Unless you are willing to go for the kill, do the prep and line the tank proper a new tank is the way to go. Your kill rate will be 100%

G,
How bad is the rust? Just revived an 8N that had a rusty tank. The amount of rust was moderate and left it as it was and have had no problems except for rust showing up in the sediment bowl. Will clean system as needed. HTH

Through the outlet hole where the sediment bowl screws in.
I have a fill cap that wont leak, when the tank is turned over. I stick the anode through the hole with a insulator so it wont short against the tank.
LOL, The one I did, had so much rust stuck to the rod the first time, that I had to pull pretty hard to get it out the small hole.
This process takes a while but, saved me a few bucks on a new aftermarket tank.

I a think it is more trouble than it is worth. tried it on a few parts, wouldn't even try it on a tank. JMHO

Thanks for the feedback! I am wanting to try electrolysis on some various parts and the question about gas tanks came to mind. Not planning to do one. I imagine if it's bad enough to need electrolysis, it's not far from becoming porous and not worth the effort.

HFJ · Jan 21, 2017

i haven't tried it. heck, i'm too lazy to shave, so i'd be a good candidate

Tom N MS · Jan 21, 2017

I agree..

Keep in mind that even though electrolysis is merely water and
soap, the gasses given off can be explosive. Plan accordingly.

I have not used electrolysis on gas tanks, nor would try. Your trusty local radiator shop guy can clean the gas tank however and that's where I'd go. Once cleaned and rust removed, products are available such as POR-15 and RED KOTE to coat the inside and from what I've read from fellas who've used them it works very well. If'N it were me, since the tank is off the hood/tractor now, I'd take it to be cleaned by a pro, then coated inside with something. Just seems logical.
