I have a simple fix for those with NACA style fuel vents. I cut a piece of 1/4 inch thick Scotch-Brite abrasive (fuel resistant, the green stuff you use to scuff aluminum) into a rectangle, and then tucked it into the fuel vent behind the lip of the NACA scoop. It is fine enough to keep out the bugs. It has high porosity allowing air to flow through easily. And the large cross sectional area in the NACA scoop prior to the transition to the round vent tube is more than large enough to assure negligible air flow restriction. Air flow, yes! Bugs, no!
