I blew it, I was no being careful enough and throwing things in to the back of the truck and I totaled the compression tube coming from the bottom of the compressor to the bottom tank, I noticed it wasn't copper. the one going from the top of the tanks to the lLF10-4H switch should be replaced. Can one purchase them or shall I make them? If I make them what should I use as far as tube and size and etc....?
