Dale,

That is a good question. I would say "yes" as my 79 arrived to me with such a replacement accumulator. Its hose was tie wrapped to the pump tray with a sheet metal screw plugging it and a hose clamp around. Since I noticed that, I learned the vent was a safety measure to allow fuel to be safely kept within the system if the diaphragm leaked, and it made sense the accumulator could not vent the tank.

But, this same car is the only one in my fleet that goes pffft when I pull the gas cap off in the summer. The air quality folks mark the cap as failed when I get it tested, but somehow do not give me any incentive, like a failed test, to do anything about it.

So, I'd say I think you should plug it.
