Hello Guys

A friend of mine is in need of help.
He has a YS 140L Focus but he's having problem in setting up the fueling system ( I am not familiar with this engine, only with a YS120FZ).
Can one place a Tee and fuel dot between tank and engine without causing fuel from entering the engine side while fueling the plane???

Look at the fact sheet at www.probuild-uk.co.uk on YS engines. I think that they have a diagram on how to set it up. I went by that, and mine goes well.
