Got Coach working... I removed one of the overflow tubes (there were 2 so I still have one) and connected an adaptor nipple to the opening where that overflow was. Installed a short hose to that connection and ran it through the hole in the floor where the overflow tube ran. Sealed around the hole with urethane adhesive. Mounted the other end of the hose in the bay behind the electrical bay so it would be separated from both the electrical stuff and the waste tanks. I filled the tank, turned on the pump, and everything works like a champ!
Thanks a ton to everybody who took the time to read and respond to my question... being a noob to RV I'm sure I will have more! I do auto glass for a living and I've done a bunch of RV windows so if anybody has glass questions please feel free to PM me.
