This is directed to
builders of the early 235s. I bought an 'almost complete' project, kit no.
11. The wing tanks each have two vent outlets. One I have traced to
to top of the tank near the gascap. The other outlet at the root also
vents into the wing tank, as confirmed by pressure buildup, with cap, outlet and
other vent plugged.
I can't find any indication
in the builders book of where in the fuel tank this vent might originate ..
i.e. up high, or possibly down low, perhaps to serve as part of a sight-gage
outlet.
Would appreciate any info
or suggestions from builders of this early version, who might recall discussion
among fellow builders back then.
Thanks,

Terrance,
The only wing fuel tank vent specified
in the 235 builders manual and on the plans is the one you indicate that is
routed from near the fuel filler cap to the bottom of the wing tip.
The other mystery vent would be a builder addition. The only other
additional tank tubes indicated in the manual and plans was an optional
site gage with tubes in the header tank.
No doubt you have used and mirror and
light to search for the other end of the tube in the tank.
