M_Boats: Yellow flem in my fuel line

I have found something I can't explain. I have a brand new Tohatsu 6 with a brand new tank and brand new fuel line. The last two times I took Seafrog out, I had trouble pumping fuel to the engine. I disconnected the fuel line from the engine, pushed in the springloaded release and pumped. Nada. Then I disconnected it at the tank thinking the fuel pickup wasn't down into the fuel. That's when I saw this yellow thick flem in the pickup tube. I shook it out and replaced the fuel line into the tank. I pumped the bulb while holding in the springloaded valve and it pumped out more of this yuck. The gas is fresh. Is there a possibility that this is an ethanol issue? Joe Seafrog M-17
