OK,
did some searching today after some reading on gas caps for the ramp truck and the very strong gas smell inside the cab. I found a thread from a while back and didn't save it. It was about modifing the vented gas cap to work better by cutting the spring off. So after reading the thread I went and got my old cap and started to take it a part.
Turn it over and take a small screw driver to the 2 small tangs that hold the ring in place. Bend the rings out straight. Pull the ring out. The black plastic part will come out also. The cap will look like the last picture. You have a rubber seal that moves around and if you look close there are two small weep holes also.

Next.
