... the one that leads to the carbon canaster
and this is all located at the drivers side - rear- wheels.....
so---- seems this might be a function of this " different separator" --
only on 73s? ...

I remember JimB making a comment about '73's and a box of chocolates. You never know what you'll get. Each '73 is a little different.
I do know that there was a fuel/vapor separator that had a return line to the side of the main tank. I understand it did not make it to the production GMC's (at least not very many) but the connection on the side of the main tank did. (And this unused connection has to be plugged.)

Interesting question. I'd like to know exactly what the restrictor does. If it allows some pressure to build up in the fuel tanks, it could reduce the vapor lock problem -- sort of along the lines I proposed by sealing the connection but in a more thought out way. Since I completely replaced all my fuel/vapor lines, if there was a restrictor in one of them, it's gone.

My guess was to try and keep too much air from getting into the manifold and messing with the air/fuel mixture.
