I have a "Super Flying Models" Eindecker ARF that is just about ready for it's first flight. I have a question about fueling. I installed the line to the engine and the muffler line per the instructions but with the cowling on, how do you fill it? I assume I need to get to the engine line and fill through that but it is pretty difficult to get to with the cowling on. Do I need to go to a three line setup?

Thanks for any suggestions.

Going to 3 lines will make it a lot easier. Just add the 3rd line and get a Fuel dot to mount on the cowl. Easy and virtually nothing to wear out, as with some fuelers.
