Do you think reducing the height of the lip would reduce the effect?
Richard's lip was .75" in the front and tapers down to .50" in the back.
How does that compare with the size you used? Could this be sized to the
larger Cessna engines he referenced and needs scaling down for our
smaller engines and cleaner airframe?
My fuel vent is between the fuel tank and the aft surface of the canard
and it drops about 3-4" below the bottom of the fuselage on the
passenger side. Is that too close?

This technique definitely works. I have used it in the past with good
results. There are 2 problems that you should be aware of though. The
creates a large low pressure area and you don't want a fuel vent
anywhere near it
(measured in feet, not inches - experience). It creates a lot of drag.
