Tank vents doen for both left and right tanks. The outboard end is simply open to the tank inteerior and the inboard end needs to have an AN fitting put on and then a flare made to mate up with the connector that is attached to the end rib and sealed into place. The fuel strainer fittings are installed with sealant into the end ribs. After a lot of research I bought some Loctite 567 sealant to use for these connections. There is one extra opening that is to be plugged for our use and that is a simple plug that gets thread sealant and is tightened.
