Fuel pump push rod

[John Gibson]

I have an original 1933 aluminum intake manifold that was modified per Ford Service Bulletin Nov-Dec 1933 to use the later 34 onward fuel pumps. See page 135 in the reprinted book. The distance from the top of this manifold for the fuel pump attachment to the base is 2.342 inches and on my 1936 aluminum manifold the distance is only 1.358 inches. The Green Book lists only three V8 fuel pump rods;
18-9400 B which is 8.10 inches for the 32-33 only fuel pump
48-9400 A which is 8.872 inches and is for the cast iron manifold
48-9400 B which is 7.872 inches and is for the aluminum manifold.

My question is; what fuel pump rod is correct for the 1933 manifold in the photo?

Thank,
John
