Dan, I learned to dive by building a hookah. I had no money but I salvaged a 2 stroke lawn mower engine, found 2 very used second stages for cheap at a scuba shop, and splurged on a brand new oil-less compressor and 2 harnesses with one way valves to mount the regs. Built the floats out of big PVC and used them for air storage. Yeah, the air smelled like glue for awhile. It put out about 50 psi. I had two 25 foot air hoses and sometimes I connected them together and went down until the hoses wouldn't let me go anymore. At that point I had to breathe slow and steady, but I could breathe.
Hook up your reg, turn the tank on and off and breath while you watch the spg. You can breathe it to zero. At 60 feet you could only breathe it to 26 psi.
Now you are comparing apple with orange. 50' line would give 7 x more volume than 90" line plus your big PVC air storage at 50 psi.
