Need a decent fuel filler valve, giant scale
One neat trick that I noticed was when a guy used a "T" in the vent line. One leg goes to the tank vent. Another leg goes outside the bottom of the airplane (normally plugged). The other leg has a check valve which lets air in to the tank vent but does not let fuel spray on the airplane during manuvers or drip out while walking the plane down the taxi way. Of course, I'm talking about a gasoline engine. This line is never capped off. When he fills the tank, he removes the plug from the vent line and replugs it when finished filling.
Does anyone know where I can get one of these check valves? One answer might be: " Go down to your local chainsaw repair shop and ask for one". When I do that they open this humongous parts book and ask "What brand chainsaw was that" with a big blank stare. I haven't had much luck getting anything at a chainsaw shop unless it's for a chain saw.
