RE: refueling
Twelve bucks for that darn fueler, plus you have to have the special end to use it. No thanks. I have a hard enough time keeping track of the little adapter I made to fill air retracts.
Although it does make the tank noiser, I think the two clunk setup is the best way to go. Not to mention, if you start having fuel problems, you can always switch your fuel line to the other clunk and rule out a split line in the tank, or keep flying for the day if you don't feel like pulling the tank out.
KISS..... words to live by.
