I am obv. new to the hobby, but my question is...
My new plane has three fuel lines. My trainer only had two. Fuel line and exhaust line. The third line is for refueling,. My question is when using the refueling line, and everything is hiden behind the cowl, how do you know when it full.. will fuel overflow from the exhaust? do you feel the pressure.. im just not sure how to know how to tell it full, and dont want to flood or make a mess of everthing. thanks alot and look forward to your advice.
