Can a car fix itself? TELL YOUR STORY!

Not a Mopar, but my KZ1000.

This was a basket case build that was in really rough shape. After I got the tank painted I knew I need a new fuel petcock. I tracked down a NOS petcock (not cheap), popped it on, made sure all was snug, filled it with gas and went for a ride. When I got home I realized fuel was weeping past the petcock lever O ring. I blew it off for a week while I was busy at work and the following week I wiped it down and viola! No more leak!

I figure it just took a little time for the fuel to swell the O ring. No magic, but it made me happy nevertheless.
