Fuel Tank holes & holes....

[MarcoPolo]

Removed the fuel tank, cleaned the bottom, chipped off the rust..

got about 1/2 dozen holes, the largest being just under 1/4 inch.

Will POR15 work best in this case? Should I use some J-B Weld on it first and then apply the POR?

Thanx for the ideas and tips

um dont think por15 is for filling holes. maybe they make an epoxy i dont know about. if you have a welder patch the holes then por15 the tank.

um if you didnt know gas tanks have gas in them, gas and gas fumes burn when welded on. dont blow yourself up

Well if youre really gonna follow this thru, weld it up. If youre worried about it, take it to a radiator shop and have them "tin it" ..... Its been said here before. And its def a great alternative to guessing if it gone done right. Costs $45- $100 depending on the extent of fixes. Youve done all the hardwork so it might be cheaper.

I know and have tested JB weld fixes. I dont let them stay that way though. Once back in I either replace it or cut and weld a new section. Its for my piece of mind.

Get a different tank, or weld in a new bottom. Any rust pit that has gone all the way through will be surrounded by that many more that havent quite gone through yet. If you do use epoxy, get a can of gas tank sealer (sloshing compound) and finish off with that. Remember, that tank is in the cab with you...

I'd get a new tank. I had my tank brazed two years ago and afterwards I went looking for a spare. Now there is a spare on the shelf for the next time this one starts to leak.

The old tank has brass spots all over it where we had to braze pinholes.

Hhmmmm...sounds of consense's points to a new tank vs. dealing with the old....

Fiber glass it until your new tank arrives.

Got a lead on a couple tanks locally. We'll see what works out.

Thanx all

I used used JB weld and then covered it with a 2 part epoxy that is used to repair aircraft fuel tanks. The repair has lasted about 8 years. I did notice some rust in the fuel filter the last time I replaced it. If there is rust on the outside then there is rust on the inside. I'll replace it when it starts leaking again. Good luck.

Later,

FWIW, I just got two days ago a new OEM steel tank from the dealer, 270 bucks plus tax shipped to MI from CA.

Its purdy nice.

I think Cdan might be able to get them cheaper. But with Michigans economy right now I wanted to keep a few dollars at home.

Fiber glass it until your new tank arrives.

Thats what I have done. Works fine.

POR-15 makes a repair kit that is meant to covers holes in a fuel tank. Even if you get a new tank, I would recommend using a POR-15 sealing kit and you will not have any rust problems.

Did just that

Thanks all

edit: also added JB Weld over the bottom before doing the POR15
