I should have made my first post a little more clear - but I think you guys have gotten me on the right track. My engine is a two stroke mounted on its side (which is why it floods when fuel goes into the muffler?) with a pitts muffler flowing out the bottom. The pressure line to the muffler and the fuel line to the carb are impossible to get to without removing the cowling (which I obviously don't want to do every time I fuel). If I were to put a "T" in the pressure line, and plug it for flight and unplug it during fueling, would fuel not go through the pitts muffler if I were to come up with two plugs? I hope I am making sense.
