gas cap not holding pressure?

3 years, no problems..? If it ain't broke don't fix it!

a little OT

does this happen to anyone else..

when your pumping the pump keeps stoping (when it thinks the tank is full from pressure) every 2 seconds

I used to have that problem. Next time you pump your gas don't stick nozzle all the way in. hold it out just little bit. problem solved

The only time either of my mustangs hiss is if I am running on fumes.
