How to make your own locking gas cap

Thanks, trapster. Even I can 'see' what you're describing. This is the kind of info that makes FABO what it is.

If I could only get the cap back that my wife forgot on a pump, it would all be good...:sad7:

This is a good candidate for a 'sticky'.

Now, can y'all tell me how to prevent spilling gas when the tank's full????
