The LH tank vents directly outside, while the RH tank vent

Not according to my manual, which has a T fitting feeding air to both
tanks from the one vent on all models. It wouldn't be the first time
the
reality differed from the manuals, of course.

Must have changed at some point. Both of ours have the vent
feeding through a check valve into the LH tank, and a crossover vent
connection between the inboard walls of both tanks.



Might depend on the year of manufacture 9 my books are for the mid
seenites airplanes) and /or the manufacturer.

You're just feeding a troll. All he does is repeat what he is told.
Very much like MX.



MX isn't told anything.


I suppose since you were born with the aviation gene you don't need to
be told anything, eh?

Nope.


Wonder how I would know that, BTW?

The Citabria's fuel system is okay now; those who guessed "filler
caps" have the satisfaction of being right. The A&P had time to give
the system a good look late last week and we tested the fix with some
local and cross-country flying over the weekend. The left tank still
tends to contribute a bit more than the right in flight, but "it's
always done that." And the system now crossflows on the ground when
the wings are not level, which it had stopped doing.

Thanks for startingthe topic. This is good stuff to know. One recently
checked out on a Citabria at one of my FBO's and I'll keep what you found
out in mind.
