Andy,
I don't know the numbers on the side of the pump.  I replaced mine a number of  years ago and I could read any numbers either.
I replaced mine with this: http://commerce1.cera.net/tacbusparts/sections/catalog/part.asp?cat_id=1531&part_id=1989
My opinion is there is nothing special about the OEM pump, just needs to be 12 volts and rated for pumping engine coolant.  TAC has multiple options - I just picked one that I thought would work fine and it seems to do so.

In hindsight, the Groco pump seems to look more like the OEM with pipe thread fittings: http://commerce1.cera.net/tacbusparts/sections/catalog/part.asp?cat_id=1530&part_id=1614

When I mounted the new pump I reversed the orientation so the motor was on top.  I figured if it leaks I don't want coolant inside the motor.

Thanks John, good information with my 6/92 I have installed a 12by 24 cooler behind the passenger side front grill and added a three way valve and tee to pump water through and help the cooling when in the mountains , with the 3/4 lines from the heater it should help. I got the idea from Kent Speer , he did this on his first coach. Thanks again.
