I have a 71 Plymouth CA car.
I am replacing the tank with the 4 vent model and going to connect to factory standards as long as the Evaporator tank is functional.
So the question is not with the new tank or how it needs to be hooked up.
I get all of that. Evap line to breather, fuel return to correct filter. Etc.
The problem is my existing tank has 5 vents on the side.
What is this and why?
I can not find any inf on this.
Please post your knowledge of this, what seems to be some sort of rare tank.
