Recently I saw a used "slimline" tank advertised for sale as "hard to find" -- at least it didn't say "rare" -- ad stated that the tank needed a lot of work, for sale at $175.

I have one of these tanks that I was going to use but went with a Home Market tank instead. About five years ago, I brought the slimline to Don Hutchinson for his re-working, media blast, pressure test, weld leaks, solder filler neck, pressure test again. After the media blast and pressure test, it was found to be leaking like a sieve, it seems like the paint had been holding the fuel in. So we didn't go any further at the time, and I hung it in the garage. It sure looks a lot better to me than the one advertised at $175.

So now I want to decide, sell it to someone who needs it, keep it as is for future use on my '71, or start repairing it for my own use. Just a couple of small dings, and one spot repaired with a nail, it appears.

Questions --

Are these tanks hard to find?

What are they "worth"?

Best ways to repair -- remove braze? weld plates over the sieve areas?

That tank is stuffed virtually beyound repair.
Firstly it is cracking along the stressed area of the lip and that tels me it needs to be annealed.
The chances of that being done without distorting the tank is very low

Secondly the idiot moron who attacked the tank with the wrong material went in way too hot, thus the pinholes in the fill .
Having had copper baked into the steel you can no longer weld it with proper steel rods necause the copped diffuses into the steel.

You might be able to get a silver solder ( not solder with 1% silver ) to take, but it will be hit & miss and all of that crud has to be ground off.
Silver solder will join but it will not fill in the holes which will probably burn back the instant you touch it with a torch.
If you can get the splits welded up, the pinholes can be covered over with lead wipe, but there is a limit to how big a hole it can bridge.

That tank is as common as breathing, there is no shortage of them and I think MIke Riley still has them NOS.
So IMHO worth keeping becaue eventually they might become rare or to use as a pattern but not economic to repair.

The cracks around the seams are common on those tanks.
Pin holes mean the tank is very rusty inside and you could be chasing them forever

Thanks, Trevor, Steve.

That's what I was thinking, but I remind myself often, "Don't believe everything you think."

Funny that a respected dealer called his tank hard-to-find. Maybe depends where you're at.

I don't mind that my tank was blasted aggressively. Otherwise, I might have painted a paper-thin tank that would have come apart in service.

So I'll just hang it from the garage rafters again, until it becomes *rare* -- I should live so long.
