Pinhole's in gas tank

[maj16]

Any suggestions on how to fix 5 pinholes in a plastic tank? Nieghbor was putting a seat cover on and inadvertently stapled into the underside of the gas tank. Now there are 5 small holes leaking fuel.

I patched boat trim oil container with JB weld & might be worth a try on your gas tank.

Go to a auto bodyshop, they have special adhesives for all types of plastic, they should be able to repair that.

Try Epoxy resin glue. Can be found at Lowes and Home depot

like jim said go to a body shop there are a couple repair adhesives depending on the type of plastic it it or they might be able to plastic weld it.

There are lots of good plastic adhesives. What's important is that you get one made to be in contact with Gasoline! Otherwise it may just eat through the bond eventually.

Plastic welding, if done with a hot air gun, would work well. Could be hard to find someone with one, but that would work, as you would be using the same material, and not worry about delamination. I have welded up a 4" split in a dirt bike tank (impacted by a steel front fender on a mini bike) and it worked great. no leaks, but wasnt real pretty.

Try using a soldering gun and melt the tiny holes back in.

Sure...that's easy!

Get some sheet metal screws, drill out each hole and put a dob of (glue all...or whatever works with gasoline) and screw the hole closed. Cover the bottom with some duct tape, and thin piece of styrofoam to protect the heads from coming in contact with tunnel...and your good to go.

I have even fixed truck gas tanks while they dripped, with this and it lasts forever.

I would plastic weld it also.
Fill the tank with water(to be really safe) and use a torch to heat up a flat blade screwdriver, get it pretty hot, then just touch the holes with the screwdriver and the holes close right up.

Thanks for all the suggestions. Spoke to a body shop, he is going to fix it for $25! Can't beat that!
