You should be able to find a replacement diaphragm. I'm not sure of a source though...but I do know people have replaced them. It would definitely be much easier to fix what you have then to try and figure out how to change it over to electric. If you really don't want to use the vacuum you could always make up some linkage/cable to operate the rear end instead of the vacuum can.
