I agree w/good idea on hyd hose for airlines. Thanks for pictures. I don't have way of making hoses @ home, but have always had local implement dealer make them for me where I need to make sharp bends in airlines, or something that's going to be moving a lot, like one of our auto-recoil air reels that also pivots. Making them at home has always been another mental project never done. Though, we do make our own 1/4, 3/8, & 1/2 air hose now w/slip-on fittings that never-ever give up.

But-anyway, what's wrong w/PEX for airline? I understand the pvc explosion thing, but I haven't been able to get any dangerous reactions from PEX.

Also-for extra air supply, I always recommend just procuring (buying?) an old 300-500-1000 gal LP tank & plumb it in to your system. The wall thickness on LP tanks is 20 times that of store-bought air tanks.
