Vented caps on top of a wing is a bad idea...The low air pressure will
suck on the fuel, leading possibly to fuel starvation or( potentially
worse) vapour lock.
Lots of airplanes get away with this set up but it is not a good design.
Why Zac does not standardise on a vent tube thru the bottom of the wing
(into HIGH pressure air) is beyond me.
Pull your tanks and install the tubes, at the very least it will set
your mind at rest.

601HDS 400 hours 2* electric pumps in wing roots.

Very probably, although I would hope there is a better solution than the
awful manual plunger...For my Stratus I have a primer solenoid and take
the head pressure from the electric pumps to do my priming for me.
There is a Lycoming group on Matronics that has some incredibly
knowledgable people. I would post your question there.
