Re: leaky fuel cap
Sorry about no photos guys but I cant find my camera just now but I will try later.
In the mean time though cabinfever1977 guessed right about the placement of the new vent,on the top center of the chrome side.
As for the sealing part of the operation, you will notice that the seam where the top chrome piece and the inner gold half come together is not perfect.
Seal this with something impervious to gas along with the single small hole up under the lip.(NOT the holes down by the locking mechanism.)
I hope this helps because those fuel caps are unacceptable as is.
