All Ercoupes after the 415-C model have unvented fuel caps. The wing tanks are "treated as a single tank" insofar as the balancing tube between them which maintains the same level in each tank, and each wing tank has a separate "overflow/fuel return/vent line into a tee from the fuselage tank standpipe which maintains the fuel level in that tank. All that has changed is that the fuselage tank is no longer present. I would think "...appropriate plumbing to connect the air spaces in the two [wing] tanks could be much as Eliacim suggests, i.e. a vent line from each tank to a tee venting to the outside on the right or left side of the fuselage at or above the level of the bottom of the original fuselage tank. Fly the plane with a manometer connected to such a fitting and angle it forward or backward for neutral or slightly negative pressure, and Voila! (?)
