Leaking gas caps???
 

I have aftermarket locking gas caps with broken seals... Where can I find new rubber seals, or do I have to buy new caps? I am losing gas out the tanks when I corner right, like on exits... Makes a dirty mess out of the sheetmetal, too! I am thinking this will increase my fuel mileage, too... Heh heh!
The caps can be air tight, right? Isn't there a vent tube on the pre- '77 trucks?
Looking for local (Calgary) supplier for the seals... Thanks!

Leaking gas caps???
 

My caps are Motorcraft locking units, so I would like to find seals for them instead of new ones, since I can't find any like it. I bought a temporary 13 dollar black plastic cap that looks like cheese on a marshmello but looks like it is working ok...
