67 mustang gas tank pressure

Recently got a 67 fastback and discovered a lot of pressure builds up in the
gas tank. It is bad even when the tank is only a quarter full. one day gas
was running out the gas cap when it was parked uphill. Is there a fix to
vent the pressure problem? Linda

Either your cap is defective or it is the wrong cap.
The cap should be the vented type.
