Re: The tale of two fuel pumps cont.

The pump with the two "lids" and the flared fitting connections is the 37-50 style. For 51-54, the cast base with hose bibb connections was introduced. The pumps fit and function the same, just updated the connections for 51-54, which also eliminated some of the possible leak points. Suggest you rebuild the correct, later style, fuel pump or have Feltz Terrill, Terrill Machine do it. He should have this on the shelf and you'd have it next day. If you want, I will trade you a later core for the earlier core. Could send directly to Terrill if you want, as I have another fuel pump I need to send him anyway.
The carburetor is a Carter WGD 784S from the 51-200. The correct carb for the 400 is a Carter 767S, nearly the same, but jetted differently for the 327 vs. 288 engine.
