fuel pump question

[Deleted User]

Can anyone tell me what the purpose is of the little domed dohickey that stands vertically at the fuel outlet port on a two-stage pump for a '53 Hornet? Its about maybe an inch and a half high, and maybe 3/4 inch in diameter, and appears to be screwed into the housing in such a way as to having access to the pressurized fuel being sent to the carburators.
The reason I ask is because I ordered a rebuilt pump from Kanter, and the one they sent me dosen't have this thing on it like my other two cars do. There is just a blind hole there in Kanters pump, not deep enough to penetrate the fuel outlet port, and no threads in the hole either.
Could that thing be something like an accumulator ( like in a motorhome water system )? Do I need to drill out the hole and thread it to accept one of these, or just ignore it and install the pump as is?

Yes, it IS a small accumulator, intended to dampen the pressure pulses somewhat. All's well without it.

Thanks Park, I'll install this one as it is then.
