I do not know your exact pump in a 93. This is common standard Shurflo pump found in most TT's today as the base pump. The exact model in your 93 if it is original may now be replaced by another model.
Classic Series Water Pump - SHURflo
However, Shurflo makes many models that are an upgrade the the basic pump.
Here is one of them.
SHURfloŽ Premium Plus Pump - SHURflo
There are others as well.
I do recommend that you add a strainer to the suction side of the pump if yours does not have one. Nay piece of dirt/debris that can get in the pumps can affect the internal check valves and make them leak over time.
Hope this helps
John
