Go with OEM from Riffraff. I have had a problem with the last 2 water pumps I got from AutoZone. First one only lasted 6k miles and the second leaked on install. But I do use their tools. Just a deposit for the tools and a full refund when returned.

If you get the tools from AutoZone get the kit for the 7.3 and the kit for a 4.9. Use the fan wench from the 7.3 kit and the pulley holder from the 4.9 kit. Pulley holder in 7.3 kit is difficult to use if you are working alone.
