Compressor air system

I put in a compressor air system in my new shed, I used 1/2" black steel and galv pipe for the pipe lines, reduced to 1/4" of course, black iron and galv pipe is rated for air supply use by ansi, I used a male quick connect plug at 1 end of the system so I simply plug the compressor in with a air line. I have 3 air supplys, 2 with good regulators ( there inside, the others supply is outside for an outside supply ) and 1 that will get a regulator pretty soon, the regulators are the best 1's sears had and they flow excelent. I put in 2 storage tanks, they are carry tanks that, I reduced doen to 1/4" and I threaded the universal tire valve linesinto a T and plugged them in that way, works great, I put a ball valve just b4 them so I don't need them if I don't need to use the extra volume. I bought 1 1/4" preassure gauge with a T near 1 of the regulators. Funny thing is the shed is only 8'x8', it is overkill but, sometimes overkill is good.
