Terry,
I'm NOT looking at any documentation but here is what I remember. Mounted on the top of each tank is a vent fitting. It is all by it's self and not part of the pick up assembly that you removed to get to the socks. The two fittings (one from each tank) are hooked by a hose to a TEE just sitting somewhere on top of the tanks. It is probably on top of the rear tank. From that "tee" another hose runs to a the fuel separater mounted in the left wheel well. A second hose from the fuel separater runs along the frame rail to the front charcoal canister. If you have a California coach like mine there will be two fuel canisters plumbed in series.
One note on that separater. It is a floating ball check valve that is suppose to shut off if liquid gasoline enters to prevent liquid from entering the line to the charcoal canister. So connecting the correct line to the each port of the separator is important there.
I hope this is the info that you wanted.
