Hey guys I send a seperate instructional image to show how to trim the intake hose adapters. The hoses I use are five ply and should be stable, te problem arises with the oil from the crank case vapor. The amount of oil makes a big difference in how much oil can seep into the spaces or voids. Once oil gets on the compressor housing hose mount it must be cleaned off with brake cleaner or the like to restore the dry surface. Nothing sliker than silicone hoses and oil coating. Hope this helps. Been away, lost.
