Danger in separating compressor head from tank? Answered

Wasn't sure where else to put this, I'm trying to turn an old ambulance into a shop truck and I'd like to use the stock giant O2 tanks on the side as the reservoir for pneumatic tools. How dangerous would it be to rig the compressor head somewhere else in the truck and pipe the air to the tanks?
I'd of course include a pressure release valve and some sort of cup to catch moisture since these tanks wouldn't have a bottom valve (though I doubt a full on air dryer would be practical). I was hoping to use flexible tubing to run the air but I doubt that would be safe at tank pressure. Would black iron and pipe tape be enough? Am I setting myself up for a world of hurt?

These tanks would be powering pneumatic tools and possibly a media blaster, thanks for any advice,
Mac

Usually O2 tanks are filled to greater than 2000psi and the out pressure is regulated with a pressure regulator. If these are standard green O2 tanks, you're in luck. I don't know about these tanks (yours) in particular, you may have to ask someone who has dealt with them. Most shop compressors are less than 200psi, and usually only about 125psi. A flexible reinforced hose, made for air systems would be sufficient. It would allow for the vibrations and movements present in a moving vehicle and your compressor, whereas a hard pipe system can weaken over time with metal fatigue caused by these vibrations. Another choice is to hard pipe the delivery system and cap each end with a hose to separate the vibrating compressor from the piping.
