In my opinion, not really but others may have different ideas. Packard did install them, after all. If your pump no longer has the fitting or a spot for it then not sure how hard it would be to find or make one out of modern fittings--so a consideration.

It is an air dome whose purpose is to smooth any severe pulsations out of the pump--sort of like an air chamber in the line eliminates the water hammer in a house. I guess if pulsations were really bad, it could cause the float valve to unseat sometime but not something I have heard being a common issue. Not all pumps had them and I believe they were pretty much eliminated by the 54 models.
