I also use the later '47-'48 glass bowl fuel pumps on my '35's with original 21 stud engines. I rebuilt maybe six or eight of these pumps in '05-'06 with new parts as necessary and some good help/advice from Ken ct on correct diaphragm material to use, how to pick correct springs to use under the diaphragm, what type of gasket material to use at the glass bowl, where to get filters for the bowls, plus some of his "trade tips" on to make them reliable etc., etc. I was determined (hell bent) to build my own pumps just because it was something I was annal enough about doing myself just to prove to myself that I could do it. Did the some thing with about 12 Stromberg carburetors with help from Ken ct and Uncle Max. Again, just because I wanted to understand all or most of the ins and outs of how they function and to prove to myself that I could do it successfully and correct. After, I had all these pumps and carbs completed, and the smoke cleared, it probably wound up costing me more to build these myself than it would would to have just sent my cores to these guys and let them do the rebuilding, If I ever need more done that's more than likely the road I will take. My thinking now is to let the pros do the rebuilding of components they are most familiar with, while I do something else on my projects. Ken showed us the special diaphragms at Rhinebeck that he puts together to make these pumps work reliably for many years. So, long story short, let the guys here who specialize in rebuilding these components do their thing while you concentrate on something else needed to get your projects completed. While I am thinking about this, here are some recommendations for folks here in the Fordbarn community who can do you good...IMO
Fuel pumps = Ken ct
Carburetors = Ken ct, Uncle Max, Charlie ny, and 1952 Henry (not necessarily in any special order of preference)
Distributors = Bubba, Ken ct, Charlie ny, Skip H. (ditto on preference note above)
Water Pumps = Skip H.
Coils = Skip H.
Shocks = Bill Wzorek
Engine rebuild = Ole Ron (if you could get him), Walt Dupont, Mark Moriarty (sp) not sure he posts here, JWL he posts here but not sure he would offer his services to everyone
Transmissions = Mac VanPelt, Charlie ny
Rear Differentials = Charlie, ny, Mac VanPelt?
Steering boxes = Charlie, ny, Mac VanPelt?
Brakes = Richard Lacy
New/Repro/NOS Parts & Services = Dick Spadaro, Roy Nacewicz, C&G, Bob Drake, Dennis Carpenter*, Joblot*, Joe's Antique Auto Parts*, Speedway Motors*, MAC's*

* not active Fordbarn members (to my knowledge)
I'm sure in my haste to post this info I have missed someone/somewhere who is a great FB member and provider of good service to this community and should be on this list. Please feel free to correct/update my info on this post in any way you think appropriate.
