Last year tech did not like the location of my fuel filler cap and tank vent; it was considered to be "in the cockpit" so with the help of a friend, a few borrowed fittings from the Turbinator guys, some pop rivets, and a few lengths of thin stovepipe from Ace Hardware in Wendover, I "walled-off" the cockpit from the fuel filler & vent. The flattened-out stovepipe ran all the way to the top of the roll cage but there was zero visibility out of the right side window. Not good- but OK for a temporary fix.
This week I removed all the thin sheet metal and fabricated an isolation panel out of some scrap 0.080" 5052-H34 aluminum that I had. I riveted an extruded 2024-T3 right-angle piece to the bottom so that it could be fastened to a chassis tube. Another piece of aluminum is fastened to the top of the panel using 5 right-angle floating captive nuts. When the door is closed , it seals against a rubber strip on top of the outer edge of it. I still need to complete the caulking (3M 2000+) and install the rubber strip.
Time is getting short....
