I made the pump cover and pump - to - crankcase gaskets from silicon sheet.
I made the diaphragm from rubber dinghy patch material (probably Hypalon), but it starts to decompose after a few months.
Unlike the T type diaphragm, which is ?rivetted? to the diaphragm, the M type is fixed with a nut, so easily replaced - by the roadside if necessary.
I expect someone could point us to a diaphragm material that will last, or when I get round to it I will try to use a T type one, one of these days, when other things - like getting more than 35 mph out of the engine - get sorted.
