I fabricated the tank fuel return lines. Since I may put an engine on at some point in the future that requires a high flow fuel return line, I’m running the same size return line as the supply line (3/8″).
Unfortunately, I wasn’t thinking about the location of the capacitive fuel sender plates when I drilled the holes for the return lines, so I had to modify the plates to provide room for the lines to run through. I kept the same clearance from the line as from the ribs/stiffeners.
The return line dumps fuel into the last bay so that hot fuel returned from the engine won’t immediately be picked up and returned to the engine.
