Fuel Tank Vent Line May 28th, 2009
Here is a close up of one of the fuel tank vent lines. This is just a tube that goes along the entire length of the tank, and it terminates open on the inside near the fuel tank. It goes to a fitting on the last rib (shown removed in the picture), and eventually goes to a drain on the belly of the plane. This is so that pressure (or vacuum) doesn’t build up in the tank and causes it to burst. When I get ready to install the inboard rib, I will flare the end and hook it up to a threaded fitting. You can see the blue nut near the rib in the picture below.
This was my first time using a pipe-bender, and it wasn’t bad at all. Of course, the aluminum tube is very soft, so it is very easy to work with.
