I was visiting a shop where a Wytech was under a high$$$$$32 and was having difficult time understanding which way to install a AN -12 hose that was about 15 inches long with clocked fittings so the hook up angle fit-after hooking one end and the other being pointed the wrong angle he then undid first end and hooked other end to tank--lo and behold the other end was wrong???? finally I convinced him that he had the hose backwards and by turning it around the clocked fittings would be good( it was on a dual ss tank system that I had built, installed the hose & fittings and they were correct but he was backwards--------
Then a little later I heard a bang,bang,banging--------he was using a ratched to tigthen some bolts and banging the knurled handle of his ratchet into painted surface of frame----------eck!
