the hole on the Vespa Ciao gas cap

Jim Fitzgerald /

Should I be able to see a hole on the top of my gas cap when it is screwed on? Or should the hole just be in the rubber part that is attached to the gas cap? Because on my Vespa Ciao it doesn't look like there ever was a hole on my gas cap, just in the rubber part.

Also, if there is supposed to be a pinhole in my gas cap, wouldn't rain water be able to get inside the gas tank?

If your Ciao has the screw type gas cap it should have a tiny hole in it unless it was painted over or something. Pull the rubber liner out and look at the inside of the of the cap. Should be a tiny hole there.

The hole is so small I doubt much if any rain or water could get in through the tiny hole. The rubber liner would also help to keep water out
