Hi everyone,
I'm looking for some experienced advice. I have a 1997 Universal M25XPA. I am changing out the old Sherwood raw water pump with an Obendorfer. Both pumps mount exactly the same way using a mounting ring on the pump that mates against the block. The ring is held in place with bronze clips that are mounted to the block.
My question is, since neither Sherwood or Obendorfer provide a mounting gasket when you purchase the pump but, a gasket is available if you hunt for it; is the gasket necessary in the first place? The mounting ring is polished brass.
I have had several opinions including: No gasket needed since there is no pressure there......Blue gasket bond is all that is necessary....You must have a gasket.
Who to believe?
