Does anyone know how the 1967 Firebird gas tank venting works? My 1969 firebird has a vent tube that is connected on the neck of the gas tank, it runs thru a metal line in the trunk then goes out of the rear tail panel behind the bumper. On this 1967 firebird the fuel tank pickup has a vent tube and a fuel line. The fuel pump only has one line available for the fuel line. The vent goes nowhere. I have no idea how Pontiac vented the 1967 firebird gas tank from the factory. Does anyone now how it was suppose to work or have pictures (pictures would be very helpful).
Thanks.........
