I would like to know if the early Flathead V-8 fuel pump (without the sediment bowl) can be used on a 1950 Flathead. I understand that there will be pushrod differences, but will it physically bolt up to the 1950 mount? Or, is there a source for the correct pump without the sediment bowl?
The fuel pump stand used 1948 and before has a different pump mount size and these won't work with the '49 to '53 pumps. The later versions have a larger opening where the pump bolts to the stand. Using an earlier stand is questionable. Could be problematic if not impossible. Best idea is to use the correct parts and save yourself a big headache.
Not to argue with Glenn, he knows flatheads well, but I would think the bolt pattern is the same, with the only difference being the loop thing that the push rod sits in is bigger with an 8ba block. These pump body's were not Ford specific, but used on many many different brands with primarily only a different arm for different camshafts and engines. If you had a stash to look at, I bet you could make a hybrid with your arm and any body of the same make that fits your mount. The internal parts will be the same.
Two things, on the early pump, the push rod cup is smaller, also the mounting flange on the early pump is shorter by 3/8" . Bolt pattern is the same on both pumps.
To clarify some things, I'm not talking about the stand base bolt pattern. I'm talking about the opening where the pump mounts to the stand. They are different on the early stands. Smaller opening. The 8BA style from '49 to '53 has a larger opening. With the early pump bolted to the later stand, there would be a wide open space at the bottom of the pump flange. Not good. I ran into this problem once and once was enough. I tried it because I didn't have the right stand on hand. If any of you guys have a version of each, compare them and you will see the difference. It's very obvious. EDIT: If you can find a junk late fuel pump, I think you can swap the bases on them to eliminate the sediment bowl. I have seen late pumps with sediment bowls, also.
