To permit the venting of the tanks to each other, I needed to add a bung for the vent line. I located and drilled up the aluminum bung and will install it with blind fasteners and sealed with PR890 fuel tank sealant. The vent system for each wing will be routed from the main tank out to a wingtip vent port and connected to the aux tank via a T-fitting.
