We definitely replaced the diaphragm last time as it had the rip.  I
believe we used the new check valves as well.  (I'd bought both kits as
they weren't all that expensive and we were borrowing a shop overnight
so wouldn't have a chance to leave the car sit until the parts arrived.)
That's why I'm wondering if there might be something that I overlooked
which would cause another failure so quickly after the last "rebuild".

Thanks,
