Hot Rods Need some help identifying a couple of flathead parts please...

I have been cleaning out my garage and ran across 2 boxes of old flathead parts I am trying to figure out what they are and a reasonable price to ask for them.

The first I think will be easier. It has a FOMOCO tag on it. It is a mechanical fuel pump. The FOMOCO tag has B4A-43506. I know the B4A is an earlier ford fuel pump model, but not sure if the other bumbers mean anything more. When I bought it 10 years ago, it was bought as a working pump, but has sat in my garage in a box for the last 10 years.

The second might be tougher. A box of main bearing caps I think. I do know that they were supposed to be for a flathead. Is there anything I can look at on these in order to try to figure out what they are for?

 

Ford parts guys can decode the secret code in about as much time as it takes to read it
From what I am finding B4A means fuel pump in Ford parts venicular.

 

Looks like it is actually B4A-x350-C, guessing maybe 4350-C or 9350-C. It appears to be missing the glass bowl on the bottom

 

Probably fits a 6 cyl truck mid '50's. 9350 is basic fuel pump number. Definitely not flathead.

 

B4=1954
