I'm runnign a two line setup in my tank (one vent, one clunk line), with a fuel T between the carb and fuel dot for filling and de-fueling. My question is though, won't I flood the engine while fueling the tank?

I wanted to avoid installing a third line (with clunk) in my tank as I used to with my glow engines for fueling and defueling.

Am I missing something here?

As you can tell, this is my first gas engine (DA-50)

Thanks
