I don't understand this centralized delivery pipe. Seems to me you'd
want to draw all output from the bottom, to drain off condensate.
Am I missing something?

valve and controls aer on the output. In this way I avoided the need
for additional bosses to be welded to the tank. I also have a similar
settup with regulator/filter on the input when I want lower, regulated
pressure. I don't know how I ever got along before I blew a whole
three bucks on an old Gardner/Denver single cylinder @ cfm compressor!
Of course it cost another dollar for a 1/2HP motor to run it and about
$70.00 for controls and safety valve etc.

How long ago?

Thanks for writing!
ps, turns out my tanks don't expire for another year. Time to plan....
