Tank patching
« on: July 07, 2006, 10:34:18 AM »
I've got a few small holes (maybe an inch long, eighth of an inch wide, so maybe more of a crack) in a tank I just picked up, and i'm wondering if there's a way to patch it without welding? is there some sort of bondo-type stuff that will withstand the gas?

several of us are working on this right now - so far, as far as i know, noone has a definitive answer - search:"tank, POR-15, JB weld" and you will probably find the many threads discussing this...

best luck

I tried jbweld and it worked...for a couple tanks of gas. Then part came off or should I say just dissolved. Now I am trying something else for get what it is called. Kinda like jb marine weld. I think a jb fix would be fine BUT you would want to line the tank with por15 and use the 3rd part of it.

There is a tube of sealer called "Seal-all" it is available at Murray's, probably other places too, it is impervious to gasoline, worth a shot... :D

When I attempted to fix the hole in the top of my tank (the one I made to insert the dent puller), I used the two part fuel tank repair epoxy from Permatex.  It worked fine for about three tanks of gas before it started leaking.  I ended up buying another tank on ebay and repainting.

If I had to do this again, I would purge fumes from the tank and braze it.  I have heard good things about JB Weld, but I would not trust it as a good long term solution.

glend - well, like i said, there are many of us trying..

ken - did you seal over the top of the JB or not? i'm hoping that the por-15 over the jb will do the trick...

eldar, what do you mean by the "3rd part" of this por-15? and what is it? a putty type filler like jb?

seems this might not be as easy as i thought :-X

May seem a silly question..........

You are adverse to welding it why?

If its a paint issue.....a good TIG welder should be able to minimize the heat damage somewhat.

If your worried about explosion...a good overnight venting full of water is all I've used and never had a problem.

Guess I'm wondering why not weld it and have it fixed right and permanent?   ??? ???

I bought a POR-15 kit and it comes with a small brush and cloth strip.  What the directions say to do is to strip the paint and when it's down to the bare metal, prep the area with the metal prep, then use the brush to apply a layer of POR-15 to the outside of the tank with the holes, then apply the cloth strip over the POR-15, making sure it's flat and even, then brush more POR-15 over the cloth.

I'm sure it would take some finish work, but the POR-15 stuff is totally impervious to gasoline or diesel fuel.



I do not work for POR-15, I just am a recent convert to their products.

Has anyone heard anything about Moyer Tank Renu?  They're website is interesting reading, not sure what they charge or if it's even worth the money, but it sounds like the next best thing to a new tank.

the only reason i don't want to weld it is because i don't have the equipment myself, so it seemed kind of useless to pay to get something so small welded, i figured there was a much easier solution. maybe welding is cheaper than any of these puttys, i'm not sure.

if you can find a welder that will touch it (they are not too keen on welding on tanks of unknown history) the cost would be pretty low.  if it is properly prepped (free of paints and rust and only a couple inches of weld the cost would be minimal to have it welded.   remember you are paying for shop time so if all they have to do is drop a 1" weld on a joint then the cost would be pretty minimal....30 mins at $50/hr isn't too bad.

Just buy a pack of gum.  Chew a stick and plug the hole, then store the gum under the seat.  Doesn't stand up to gas for long so you have to change it at every fillup.  Good luck!

P.S. - Welding/brazing works alot better than gum. ::)
