For once I'm glad for plastic - LKTraz - 04-20-2016
For as much as many of us complain about plastic parts on vehicles, this time I'm glad for onbe to be plastic.
Barb's Tahoe has developed a gas leak. Pinhole in the gas tank. If it were a metal tank it would be a bitch to fix and would be just as easy to hit the junkyard and replace it. Being that it's plastic I can let J B Weld come to the rescue!
Now I just need a weekend where the temperatures will hit at least 70 during the day and be no less than 55 overnight. I'll need to glop it up good, place a piece of flat plastic over the area, glop more J B around the edges then place a larger piece of flat wood with a layer of waxed paper over that and put a bottle jack under it and apply a little pressure.
After 24 or so hours the problem should be solved!
Being that the sending unit/fuel pump needs to be replaced it will be the perfect time to also fix the leak. I'll need to drop the tank to replace the unit so while I have it down I can drain it, do the unit, remount and seal the tank and re-fill it after I check the patch job.

Or...put a small "O" ring on a sheet metal screw and run it in the hole. It's been working on my air compressor tank for a few years now. I doubt that your gas tanks gets to 100 psi.
They also used to have some stuff to fix steel tanks. It was like an epoxy, it came in two strips, you kneaded them together and smushed it on the bad spot. Worked like a fucking champ.
Found it...this shit. http://www.acehardware.com/product/index.jsp?productId=1297554&cp=2568443.2568455.1446494.1258970
PS: If you use any of my fixes don't smoke in, near, or around the car.

Epoxy putty is good for damn near anything. Not sure if that tank stuff is formulated the same but it looks similar.
I've used it to make whole replacement parts. With a little sanding and proper paint it's great for fixing ceramic figurines, or using as wood filler, car body repair, just about anything really.
