I thought out where to put the bulkhead fittings so the lines don't get in the way, then drilled and made up lines to suit. The paths are different on either side because of the flop tube in the left tank. I made 3/8" ally tube to transition the forward fuel pickup on the left fuel tank back to the bulkhead fitting through the fuselage. This precludes it having to come through into the footwell area, where the line would be visible after completion.
