I think the big thing would be to get it down to maybe 2 pieces of metal tube instead of all the silicone hose. The mandrel bends will really help with smooth flow. Ben I'll look through my pile of mandrel bends and see what I have laying around. I know I have few straight lengths,but I'm not sure on diameters. I might have some 3in around but most is 2.5

Whatever we can discuss it more in detail. I need to make a cia for my tour anyways.
