Ajax do you know how to cut into an old gas tank safely? There is a trick to it and NOT for amateurs. You;ll wake up here and there in cooked pieces if you don’t do it right. Even if a tank has been sitting for 15 yrs it will still blow. The gas permeates into the metal and locked in till heated.
Probably should have been given an insanity plea but welded on a new valve on a 10,000 gallon tank 1/2 full. When you’re hungry you do stupid things. For some reason the last gas tank I repaired spooked me and I have not welded one since.
Fill them with exhaust fumes to offset the oxygen balance. Put an airtight hose on an exhaust, preferably diesel and let it cook for 1/2 hr or more. Make sure you have an exit for the gases on the other end of the tank so it’s vented properly. Leave the exhaust running into it while cutting. I used the regular hose they use in garages to vent exhaust outside. Anything else will melt.
I have a 6,000 gallon tank done that way. Cut a straight line on the side you want the hinge on. Then weld on a piano hinge. proceed to cut out the other 3 sides of the door. Every 12 inches or so of cut cover it with duct tape to minimize any air/oxygen getting back in.
Do the door latch in a way no one can lock you inside.
