I have a "tall 50" ammo can bolted to the tongue of my utility trailer. Damn thing is leaking, and I don't know why. I swapped lids with a brand new one with a very pliable gasket - no change, it shows good indentation all around. No rust anywhere. I went out this AM to check it after yesterday's rain, it actually hissed from pressure when I opened it - yet there was water in it.
Any ideas?
