Guys, I know this is not necessarily not old Ford but I'm just trying to get it out there.
Sometimes I wish I could just say NO!
I have a positive displacement water pump from a WW2 amphibious vehicle. The first 3 photos show the brass housing and the diaphragm. You can see how the diaphragm has let go from the housing.
I could not tell you anything much about the material of the diaphragm besides it is very hard with the slightest amount of 'give' when you push into it.
The forth photo is of the rotating pump which spins inside the diaphragm.
If you look at the link below it shows the pump as a 'Gerotor' type pump.

Obviously it needs to withstand decent sheer type force, but temperature is not super critical because water is constantly traveling through the unit.
One of the product engineers (whatever that is?) at Henkel has been really helpful and put me on to the products and process required to rebond. So that part is sorted.
However I also require a new one be made. The brass housing is simple, the diaphragm is something else.
I have tried Jabsco and Fynspray and zip zilch.
Does anyone have thoughts on doing this.
