Probably best to rebuild
and replace all the internal rubber parts with the service kit. Thanks for lead on parts,
I just realized you're in SoCal. With the shipping
I don't know whether there will be much of a savings with DepCo, which is in the Tampa Bay area, maybe...
A couple of tips from the techs at DepCo although you may already be aware. Once you've cleaned the pump, the new rubber parts are installed dry--i.e. without any gasket material. The bolts/screws should be snug, not overly tight, as you want some give in the gasket edges. When you reinstall the Pulse Damper, start with the screws at the center of the coverplate and work
outward in a star pattern toward either end (like one does with wheel
lugs) to help keep the Damper edges flat. It is also wise to replace the toothed drive belt while you've got the thing apart although you can save the old as a temporary spare.
I also found that changing from a 40 psi to 20 psi pressure switch eliminated switch failures and some of the leakage issues in the FW system without an appreciable difference in the water supply at the fixtures. (Since doing so, I've had no switch failures and my old spare higher pressure switches have come in handy for helping other's that insist on the higher pressure for whatever reason.)
