I don't think that dual clunks will be practical from here until the day that you stop flying.

I got the 2 clunk (three line setup) idea from the guys here. It seems to me that a 2nd clunk will actually drain the fuel better (at the end of the flying session) than bent tubing inside of the tank.... but maybe not. It sure was easier though than bending tubing and getting it as close to the bottom of the tank as possible.

Hmmm time will tell. Has anyone had a problem with a 2 clunk setup?
