Yes, they should.
It is possible that if you fill your tank and then immediately park the car
in the sun on a really hot day, the fuel could expand enough to fill the
vent line all the way up to the carbon canisters in the engine bay and soak
the carbon with fuel. (You do still have the carbon canisters?)
The separator tank was mounted to the inner fender by using an existing
screw for the chrome trim strip with a small bracket, and a screw through
the flange where the fender joins the body. If this bracket were removed,
there would be little evidence of the tank ever having been there.
Also, the later cars (Clausager says Aug '76-on) have an additional loop of
steel hardline in the vent circuit that runs from the right rear corner of
the boot at the separator tank, forward past the bootlid hinge, across the
car to the driver side hinge, makes a U-turn and exits through a fitting in
the boot floor near the fuel pump. The idea was that if the car was rolled
upside down, the loop of line would prevent fuel from gravity feeding up to
the carbon canisters.
When I got my car, the separator tank had been removed but was still in the
boot with the screws and bracket in a plastic bag. :)
