Compressed gas can

OK not to be a A$$ hold but why are we even concerned over a easily replaced for a hundred dollar item? and I thought I was the cheapest SOB on this forum - Dude open the wallet let the moths fly out and buy a new tank.

...not even close to the cheapest...we had a guy recycling gear oil through coffee filters last year.....

Au contraire Ormondude!

Cheap? Or logical? He knows the old one doesn’t leak- it has survived a brutal torture test. If the goal is to get a tank that doesn’t leak, and I believe it is, then as mentioned here before, buying a new one is increasing the odds of ending up with one that leaks.

Not to mention that the age of the tank has nothing to do with its propensity to shrink or swell with heat.

Just another POV.

Something Freudian going on here! Not sure if we're still talking about the tank!

OK Then if its not about the money - Why Not Take a piece of fuel line and adapter clipped to the tank - Hose clamp a tire inflation valve on the end of the Fuel line - Then use a Air pump to reverse the collapse? - This way you dont risk explosion or setting yourself on fire! (however i did use the ignite gas idea on a steel motorcycle fuel tank with success) I do not recommend it for plastic plus I was under 20 at the time and henceforth invulnerable to stuff that sounds like real bad idea NOW.

Because the plastic needs to be soft for it to return to shape. And for it to be soft, it must also be hot. If it not hot, it will return to its partly collapsed state once the air pressure is released from it. It also risks damaging the tank, because the plastic is more brittle at cooler temperatures. See the postings above. There is NO risk of explosion to warm the tank in the sun at ambient temperature, because it's WELL below the auto-ignition temperature of the fuel. You are simply warming it back to around the temperature it was at when it collapsed in the first place. The vapour pressure of the already-present fuel creates only enough pressure to do the job. No tools required, no risk of excess pressure.

Isn't science wonderfull?

But a Freudian slip into cold water results in shrinkage at any age.

Wow! Did I start something controversial?! it's not a tight wallet issue it's a loose wallet issue. While $100 may not be much, it is when there are so many other $100 things going on. If I can get the the tank to work longer then that $100 goes toward another upgrade I want to do. Not to mention this isn't the only hobby I have soooo every little bit helps. Also I do want to get a bigger tank but don't want to be rushed into it.

All I can say is Air pressure Caused it Air Pressure will fix it Heat it up if you Like However once somewhat restored fill it with fuel (or Water if its cold out and season is Over) then it cant recompress without rupturing and if its So Shot it Ruptures its Toast anyway - OH BTW Hot water will make it much worse if its not kept boiling to produce steam it will simply Lower the air Pressure inside even more once it starts to cool with the top on and thats how it got so crushed to begin with. IMHO

It's the hot water I get worried about! That's why I've managed to stay out of it so far.....
