my previous thought was to do as pictured above with a very small tank (~1 qt) mounted up higher than the main tank. i would then have two main tank vents plumbed into the smaller vent tank; one line plumbed into the bottom from the filler neck and one into the bottom from the main tank. this small tank would then be vented out the top.

If you have any older Chiltons or other repair manuals for older cars, take a look at the emissions section. You should be able to find a simple diagram of how the lines are connected in a vapor recovery system with a charcoal canister.
The systems are really simple in how they work. Building one at home from OEM parts should be really easy for you after everything you have done on your project yourself.
If you build one please post pics.
