Another 2 clunk guy here. I like the added convenience of being able to drain the tank fully (huh? drain it 'fully'....
How would I drain a tank, 'fully'?)... sorry, got sidetracked.
I didn't do this on my Magic and it's kind of a pain to take the line off the engine to drain the tank after a day of flying when there is a fill line (just a tube) sitting right there.
