Group buy interest-MPS Diaphragms, Just a thought. Options

[tracks914]

I'm having FI issues right now, lots of them. Today I got to the point of taking the MPS out of my 1.7 DD and put it into my 2.0 recent resto. I was surprised to see that the MPS out of my DD wouldn't hold vacuum. Being number 4 MPS to take apart this week I was only able to find one of them with a good diaphragm and that one I put into my 2.0.
Changing them really wasn't a big deal,(2 out of 10 for difficulty) but setting them up afterwords might be trickyer. As long as the original settings were maintained the car should run better than with a cracked diaphragm????

With most of these MPS's over 35 years old, there cannot be many of them still in good condition. I would be leery of buying used only to have it fail soon after buying. How hard would it be to have a batch of 200 diaphragms made up. I'm sure they would sell.

BTW - took a good quality packing type tape and sealed up one side (outside) of the diaphragm and put it back into my DD. Very short term fix but it seemed to run a bit better for now. It can't be any worse than running with 2 big cracks 50% of the way around the old diaphragm.
