Okay, fuel selector completely rebuilt and vents checked thoroughly.  Had one plugged up with mud dauber crap. Even still, have a very slow center vent under selector leak ... about 1/2 gallon in 8-10 days.  I guess that would translate to about 1 cup a day.  Mechanic has been studying the various valves in the wheel wells and wondering ... ???? He talked to Mark but didn't get any more ideas.  He says he owes me nothing until its fixed ... like that!

What weirdness could this be ????
