Per the supplier: Yes, these do have vent holes.

Q: Can you measure the distance between the cap top flange and the highest point of the locking handle when the cap is in the locked position? I want to see if the cap will fit my Marchetti SF260. Need to see if the fuel door will close.

The distance you are requesting is approximately 2" in height.

Approx 2.5 inch diameter.
