SB Ford CSR water pump O rings

Rory McNeil · 05-08-2012, 02:03 AM

I have a used CSR electric water pump for a SB Ford. It has an aluminum plate that attatches to the stock timing cover, and the pump itself bolts to the plate. I noticed that there are grooves for O Rings in the water pump body where the pump bolts to the plate, and I am missing one of these O Rings. The O rings are not round, rather they have an irregular shape. Does anybody know if these O rings are available anywhere? Or, if I could just use a bead of good quality RTV, like "Right Stuff" instead? I currently am using the stock Ford water pump with a Moroso electric belt drive, which is wired to run "backwards", since the factory 85 Mustang 5.0 serpentine belt setup runs counter-clockwise. I should be able to run the CSR pump wired to a "normal" though, shouldn`t I?
