just a few photos of how I am running the air line on my oldsmobile.. a few years ago i had an air hose from my compressor that went bad.. well actually I accidently burnt a hole in it.. anyhow i never got around to fix so. first pic the hose in question is just large enough to slip over the 1/4 inch air line I used.
second pic shows old air hose installed over 1/4 inch air line the air hose over the air line helps reduce the chance of abrasions or holes to the small 1/4 inch airline. also and more importantly it enables the air line to be clamped with larger line clamps works great. I have used this setup on all three of my cars sawzall
I'm not sure that I understand.How bout you bring that stuff to my house and put it on my car.That'll clear it up for me.
