More good info, Bushwacker, thanks. Since I never see water in my Racors except when I'm in the Bahamas, strongly suspect my rec90 supplier is selling contaminated fuel. If not, I'd eventually get some from the bowl, either from the fuel or elsewhere. That was normal before E10 came along. Maybe there are some good suppliers locally. I need a test kit and test ethanol content in all the various fuel sources around here.
Question: how do you know that the fuel you bought that showed no water in your filter was pure Rec90 and not contaminated with enough E10 to absorb any water?
I'll check the vent hose arrangement and fuel cap Oring. What is that "special inverted U fitting on the vent hose?
