M37 fuel pump rebuild help

[junking]

Rebuilding a fuel pump for my 1952 m37. How in the world do you reconnect the diaphragms to the actuating rods?

Busted the stem of my new vacuum diaphragm and bent the old one.

Thank you

Bypass it using a 4psi 24v facet is the best way. But anyway are you sure you have the right diaphragm?

It is rather tricky to get it to fit just right. I rebuilt one awhile ago and there were a lot of nasty works spoken during the assembly. The best I can offer is to have the rod inside up as high as it can go and angle the rod in on the diaphragm. You could file the hole a bit bigger but then there is the risk of it coming off during highspeed operation.

There is a tool for that and it is in the TM. The 3rd one is the bugger.

I put on a backing plate to cover my fuel pump's site, and installed a Facet 24 V marine pump way back on the inside of my frame. I have pictures of it, if you are interested. Have 3 PSI at my carb, truck runs fine. Have it running thru a dash aircraft toggle. Got it from Pegasus Auto racing.

Thanks everyone. Still no luck. Hoping to keep as stock as possible. May buy a rebuid.

Start at page 53 of TM9-1828A. Then go to page 85 and read that. These are the two closest to our pumps.

Thank you!

The tool in the TM should help.

Page 99 of the 1952 version of this TM is a very very close match to our pumps. Plan to try again tomorrow.

Thank you

Finally got the pump back together. Reinstalling the vacuum diaphragm was real PITA. For those interested, this is what finally worked for me:

Vacuum diaphragm hook up to actuator rod:

1) I the diaphragm, spring, and center body assembly in a vice to squeeze it all together. I have a piece of wood with a hole with center rod in the hole and against the vice jaw.
2) with diaphragm spring about 80% compressed, I cocked the diaphram to slant away from where the actuator lever would be.
3) I inserted the lever assy down into the body guiding it into the diaphragm opening by looking through hole in fuel side
4) using a flat screw driver or pointed hook, I manipulated the actuator in place and realigned the angled diaphragm
5) it went back together and I did the happy dance.

My rebuild kit came with three flat diaphragms for the fuel side. Can anyone tell me if I am suppose to use one or three. Exploded view shows only one but many others have there.

Plan to reinstall this weekend.

Thanks
