I thought the Kilby deal with the mounting bracket, coalescing filter and check valve combo was pretty slick, so I bought their package. Not cheap but a nice setup and it makes it relatively easy to mount the filter to the firewall.
I had these guys make my steel braided hose:
I think it was ~ $30 for my piece with ends. Unfortunately I estimated a few inches too short but I managed to pull it together with no slack left.
My system still has a couple of leaks, but when that compressor is on the system reaches pressure FAST, and works "optimally" at around 100-110 PSI.
