well im currently in okinawa right now coming back home in december and the vehicle that i use when i go back home a 87 dodge dakota 3.7 is having some sort of issues with the pressure in the gas tank or something ive been searching the forums and cant find anything but what my friend has been explaining to me is that it runs fine but when they turn it off pressure builds up and leaks out of the gas tank and somewhere under the hood i guess. i was assuming buying a new gas cap but has anyone else had this problem before?
