Re: Identify my fuel pump

The "little thing" circled in red is just a pulse dome and shouldn't be relied on to differentiate one pump from another. It can be present or absent on all manner of pumps though more common on earlier pumps back into the 30s. In your photo #2 there may be a threaded hole and plug in the fuel outlet where the pulse dome could be attached. As a practical matter it really makes no difference in performance if it's there or the opening is plugged as is often case. It's function was to minimize the pulses of fuel and make a slightly more uniform flow. Obviously later experience by pump makers and car manufacturers showed it wasn't worth the added cost.

What brand the original pump was should have no affect on having it rebuilt, just send it to a well-regarded rebuilder like Gould Rebuilders or Terrill.
