Gas Tank leak

Don't know if this is the right forum but I have a leak in my 79 Z28 gas tank. From what I can tell its just a very small hole in the bottom that keeps leaking, I was thinking about plugging it up with a screw and a piece of rubber but i don't know how well that will work. Does any one have any suggestions for an easy/quick fix?

That hole will grow when you start to fool with it. replacement tanks are pretty reasonable and wont burn your house down. I would not recommend even fooling with a rusty tank. That little hole is just the tip of the Iceberg, I am sure that there is a bigger amount of rust than you anticipate.
I soldered a tank in a 64 falcon a few years ago. Started off looking pretty minor. Untill I was done I soldered a 6 inch square spot in the tank, I sold the car as a restorable vehicle a few month later.At least it ran so it was able to load on the transport.

You would most likely need to take it out to fix it so it would last at all. You can probably get a new tank for less than $100 so why mess with it. The spot that is rotted is most likely thin and rusty for a good area around where it is leaking so as LAtech said you will most likely end up with a huge hole.

POR15 has a gas tank sealer that you pour in the tank, but you have to remove the tank to do it, so better to fix it right.

If your just looking for a fast fix until you can get at it, just rub a bar of laundry soap over the hole area, forcing some of the soap in the hole as you rub over it.Should last a day or so.

I would have to agree with latech and "T" on this. That hole is just waiting for something to make it bigger, I don't know what they get for a new one, but whatever it is, it will be the right choice.

Only do the POR15 stuff if you can't replace it. Those are a pain to do!

There is a method to repair an old gas tank that works fine..wrap the whole tank with fiberglass using vinyl ester resin..the use of vinyl ester resin is critical as that resin will hold up to fuel..that is what we use to make tanks for boats and works fine..

That would probably cost more than a replacement . J.M.O.

That it may but knowing that can be useful if you need to repair or replace a tank that is otherwise unobtanium..lot of the things done in restoration and repair we would not do if the parts were readily available..
