Finished bending right tank return line.
Fabricated left and right tank vent lines. Lines will terminate with JDair vents. Nylon tubing will connect the vents to the line. Much easier to work with than 3/8 tubing.
Began bending brake lines, more compound curves, yaaa. There is only one thing that I enjoy compound curves on, well maybe two or three!
Finished required bends on right tank feed line. Began bending right tank return line.
Began bending right fuel tank lines.
Was able to bend and install left tank feed and return lines. Decided to deviate from my orginal plan to redo fuel line lenght. I had to construct a template. Once all the lines are run and I’m assured this will work I will transfer holes to side skins. Bending fuel tubing is definitely my least favorite and frustrating task. Lots of angles and lots of wasted time and tubing!
No real work accomplished. Spent several hours over the past few days attempting to come up with a soulution for a fuel injection return line, duplex valve, and dual pre filters at the wing root. Space is tight but I think I have a viable solution finally.
I blew up the tank profile plans to scale and taped to forward side skin to position parts and work out the bend radius. Two dimensional of course so not all the bends are shown.
In the end the lines are located slightly different with the required bends.
Made bends for feed and return lines at fuel selector.
Match drilled transponder doubler bracket.
Installed platenuts and secured fuel pumps to floor. Began fabricating fuel lines. Lots if work to get the bends close enough to call acceptable!
