 |
|
I plan on plumbing ¼ inch fuel return lines into my tanks and would like some advice on running the lines, in particular the best place to exit the tanks. I know there was some discussion on this subject recently, but can’t remember if it addressed the location of vent lines or return lines. Any advice will be appreciated.

I just ran my return lines a few weeks ago. I ran the 1/4 inch tubing from
the mid high point of the outboard tank rib baffle. It was attached to a 90
degree fitting that I prosealed and traveled aft where a 90 degree bend was
made. It then traveled in board through 1/4 inch bushings placed in the
holes through the z brackets. Another 90 degree bend was made to travel back
to a fitting that exsited the fuse.
I know some have run there line directly from the fuse into the tank making
sure that the line travels into the second bay of the tank. I really don't
know the science as to which is best. Mine, that will enter at the highest
point of the tank where fuel will hardly ever be or the ones that will
enter in board where there will usually always be fuel. I would check with
the engine / fuel injection folks to get their suggestions. I did mine per
Robbie Attaway's advice. He will be the individual that builds my ECi
engine.

Frank,
Thanks for the info. I'm also thinking about bringing them straight out
slightly aft of the vent line. I'm trying to find out the best place to exit
the end rib so it doesn't interfere with anything in the wing root.
