Replace large O ring: Model #390251981 Pump 390251981 Craftsman Pump

A:

Hello glad to help.  Thank You for choosing Sears PartsDirect.com

I am sorry and do understand your frustration when doing the work on your pump and replacing the large O ring.

You need to remove the pump housing itself.   Use either wrenches or sockets fo remove the housing (outer case).  Whiile the case is removed pull out the old gasket and install the new one.   While there look at all the gaskets and get it all done the first time.   Lubricate the o-ring before re-installing the pump housing as it can tear or break upon reassembly.

Q:

How do I prime my water pump?

A:

To prime the pump, you need to remove a pipe from the pump body and pour water into the pipes from the well until they are full.

If the pipes don't fill with water, the foot valve inside the well or a pipe inside the well is leaking. If a well pump loses prime, the problem is usually in the pipe or foot valve inside the well.
