Have an 2005 Safari that I haven't used in awhile and when I turn on the pump today I notice that the pump would not stop running. Thought it might be air in line until I notice a small amount of water coming from water pump service door. Found that pump was leaking between head and motor. Remove pump and check diaphram

on head of pump but it looks fine. Question do I need new pump or is there a pump rebuild kit. Water was flowing fine when I was using it. Pump is a SHURflo 2088-422-144.
