Below, I'm getting the proper torque on the vent line fitting using my torque wrench and crowfoot wrench.
I also sealed the baffle. It's not easy getting a good bead on the inside of the tank at the baffle since there is no access once the baffle is in place. You have to carefully lay down a line of proseal on the inside of the tank skin and let the baffle "squeegee" it into place as you lower the baffle. Too much or too little and the bead won't form correctly. The Semco sealant gun made it easy to get a properly sized and placed line of proseal which resulted in a good bead like you see below. I shot this picture with the camera held inside the first bay through the tank access hole.
