Thanks, guys. It doesn't get used that often for me to justify doing an electric conversion. I see there is an upgrade kit from the older model manual flushes. I wonder how that increases the life of the pump innards. My pump wasn't running. Over the winter I removed it and 'unfroze' it and it did work but, has since stopped. I get free pumpouts so, I will likely leave it as is.
For those that rebuilt the manual pump how difficult was it?
