My schedule is killing me and I haven't had a spare moment to run by my storage unit to see what kind of water pump I have. I guess this is a two part question: what waterpump (psi) do I have in my 2012 Grey Wolf 28BH, and what would be the best aftermarket replacement.
Don't have a local parts guy although Im sure there is one around. I did some research, these water pumps come in a range of psi ratings, and people were cautioning against straying from what your original model had. I suspect a 55psi is a middle of the road standard that wouldn't give me any problems.
