Among other things today, I fabricated the two fuel vent lines that go on the belly. I made 90-degree bends in some 6" line, then used the bandsaw to cut them at an angle that still results in good ram air flow, but keeps them relatively short. Over the years, I've read several reports about people having fuel feed problems, tank damage, and even engine failures due to insects making their homes inside the fuel vents. There are several solutions to the problem. One is to bond a piece of fine-mesh screen over the ends of the vents with proseal. Another is to insert a folded, 3" piece of 0.040" safety wire into the vent. This is the technique I used for now. We'll see how it works in the long run. I can always change it later. Finally, I inserted a rubber grommet in each of the vent holes in the gear cover plates. There is enough room inside the grommets for the plates to be easily removed without disturbing the vents.
