    I have used the material sold by Ollie for diaphragms. I bought mine through McMasters. The problem is it is not fiber reinforced so it can stretch. Not sure if Ollie’s material is or not. Fuel makes it swell. I have found it does not work well for pumps where diaphragm is also check valves. Seems to be ok for pumps where diaphragm is just a diaphragm and chamber is on larger side.
