Air Tank leak

[harv rockel]

My air tank has a small pin hole leak. Am looking for suggestions to do a repair at this time rather than buy a new tank.

If I need a new tank does anyone know where one can be purchased in Canada. Applied GMC sells them but the picture in their catalog shows a label
"Made in Canada".
The tank is 7" in diameter & 12" long. Its for a 1973 GMC Sequoia.

You may have some luck with JB Weld. I have used that on a bunch of different things with pretty good to great results.

Id scrape and scuff up the surface where the leak is, Wire wheel / sand paper. Get it clean and go for it. For a few bucks its worth a shot.

I don't think I would try and repair it. It has a pinhole because it is rusting out from the inside. Your best bet would be a stainless tank, and it
doesn't get much closer than Jim in Lethbridge. Alternatively, I have made an air tank before from an old fire extinguisher. You can usually get them
for free when they are 'de-commissioned'. You will need to weld an adapter to it, but it's fairly straightforward. Some guys have even made tanks out
of coleman propane bottles, but more fabrication is required.

I repaired a 100 gallon Compressor tank about 5 years ago. Go get a small self threading bolt or fine threaded sheet metal screw. Enlarge the hole
enough to start the screw. Put some sealant on the threads of the screw and thread it in. The metal in that area is usually very thin from internal
rusting an very difficult to weld.

I did have one that I put about 3 layers of fiber class about 1 or 1.5 " square over the hole and threaded in the bolt through the fiberglass and in
the hole while the epoxy was still wet.

A screw with JB weld might also be effective.

Air tanks are bombs. Once it leaks it's trash.
Threading a bolt into an enlarged hole in a rusty air tank and then pressurizing to 120PSI is a recipe for a bolt shot through your face or worse yet
your loved one's face when they walk by at some random point down the road.
Compressed air is not something to mess with.

Replace it with a stainless tank from JIM or a small tank from Viair.

I actually have two air tanks on my coach. The second one is a decommissioned fireman's air bottle rated at over 3000 PSI. We are only using it at
125 PSI or so and you can usually find them for free. .

As far a pressure exerted on an installed screw, it is very minimal. At 120PSI the pressure computes to be 2.4 PSI actually exerted on a 8 screw. A
little less for a #6 and slight more for a #10. That is hardly a rifle shot or anything of that nature. I have repaired many tanks over the years,
some were in commercial applications, and never had one fail. If iy really bothers you install a band clamp (radiator hose clamp) over the screw and
around the tank

Or go buy a new one if you want.

Thank you all for the input. I have ended up ordering a new tank, primarily because there was way too much rust when tried to clean it thus would
likely get more holes.
