My old tank was a used, cleaned out and fitting welded in, less than OSHA or ASME Qualified LP pressure tank with a Standpipe set in it. Took us three tries to get it pressure tight using a Lincoln Tombstone welder then Sealing the porous welds with brass and a Gas Axe over 35 years ago. Sat in my barn since bought the place in 2009, got really corrupted and I just could not risk using it again, went to scrap. Used lube oil guns in a Garage in OFallon MO years ago, similarly with a box of random assorted fittings. This will last the rest of my lifetime, into someone else's. 8 qt.
