need to patch my black tank

I accidentally drilled a hole in my black tank! What do you suggest for a patch? It's only a 1/4" hole. I'm sure there is a thread covering this somewhere, but I can't find one.

    Picked up on and used a variation of the sheet metal screw idea from other car buffs years ago when I discovered a pinhole leak in the top of a fuel tank of a my daily driver classic car until I could get a replica tank. I used the old style gas tank caulk under and on the rubber grommet, then applied a good quarter inch thick layer of the caulk over the whole screw head.

    This should do it -- a good hardware store or Lowes/Home Depot

    Stainless or brass, don't want it to come loose later - they are great - I used them to attach the Solar Panels on my unit 10 years ago.

    Hope this helps,
  • If it's around the top of the tank what about Eternabond? A friend of ours used it on there Gray tank and it held. Good luck I hope you get it repaired.
  • Don't know what adhesives you could use but there are rubber inserts that can be put in the hole. You would probably have to drill the hole to at least 3/8". The inserts are round about 1/2" long with a flange at one end and a brass thread insert in the other. Put this in the hole then thread in a machine screw with a flat washer, tighten it up and the insert expands sealing the hole. If you can't find this contact "Horst Miracle probes" and purchase one of their tank probes to seal the hole.
