I started dinking around with plumbing of the aux tank. The first thing I did was screw the finger strainer into the fuel tank. It protrudes more than I expected. Looks like I'll have to access it from the bay inboard of the aux tank bay. I don't think I can put the tank in with the finger strainer in place once the skin is riveted on. That means rather than center the tank in the bay I should favor the inboard side. I'm glad I figured that out before I cut the top skin for the filler neck.
I started planning out the run for the fuel line from the tank to the main tank. I started to wonder the best way to make the run and decided to ask the eGroup.
I’m running a ¼ line from my aux tank just off the rear spar and aft of the false spar and will “T” in at my sight gauge. My question is would it be acceptable to drill a hole in each rib the length of the run (rib 8-3) and install a grommet and run the line through it or should I install an angle bracket at each rib and use Adel clamps and run it through the lightening holes?
The response was that either is okay. It brought up the question of wither the 1/4" line was big enough. The quick build manual calls for 1/4' line so I figured it was fine.
Based on reported user experience the 3/8" tube transfers the fuel from the aux tanks to the mains in 31 minutes, the 1/4" tube transfers the fuel in 43-44 minutes. I probably will rarely used the aux tanks but when I do it's going to be used for tankering rather than endurance. I may even be on the ground when I make the transfer. I prefer to treat aux tanks as "unusable fuel" for flight planning purposes. So I'll stick with the 1/4" tubing.
