According to the 1970 Service Manual, there are two vents on the CAS tank and four on the ECS tank. All from California had the latter. I would bet yours would be the former, and therefore, two vents. Your "Vapor Liquid Separator" will tell by how many tubes it has going into it, 2 or 4. I guess that might be three or five, one goes to the engine bay.

Here's a picture for the manual illustrating the ECS system with 4 vents.

Of you have that separator, you will be able to see it in your trunk.
