Not sure Tom since I don't have the original, the one I have now has 2 wire's going in the the float and it has a pick up tube.
The other vent tube's or hoses are on the side of the tank it's self, only 1 hose or tube goes in where the float is.
I just got my catalog in and it show's from 71 up and mine is a 70, so I'm still not sure how it's supposed to look.
The 71 has 2 tube's that go in near the float for the fuel gauge. The fuel tank is molded around the wheel well so it seems to be right.
But it does look to be very small for this car since the car is so big running a 455 motor, looks to be around a 14 gallon fuel tank.
