where is fuel tank vent

E models with two overflow returns have no vent holes on wing caps. The vent air comes from the header tank vented cap. Matt isn't your G this way?

If it is like mine, the vent hole is in the gas caps and make sure they face forward. Keep them clean and clear

I'm used to a Cessna 150. You could remove the cap and see light through a hole showing the vent was open. I have a 1960 Forney F1 now but there's no holes in any of the 3 fuel caps. Hasn't been an issue but checking for a clear vent was always part of my pre flight. It must be venting from somewhere, but I'd like to verify it before each flight.

all the fuel caps on some, others just 1 cap,
