I crawled under a trailer today to get an idea of what the air line plumbing looks like on a trailer. I am having trouble distinguishing which line does what. I noticed there are two different sizes. Which one would be the hose for the red gladhand and which one would be for the blue gladhand?
I will definitely look into that today, I was going to see if there was a better option than thick fishing wire. Do you just glue it in with regular plastic cement? And can you just cut it with scissors?
