Placed the support for the red cube in the fwd tunnel. Connected the fuel lines from the pump to red cube and red cube to firewall. Needed to remove the fuel valve to attach the steel braided fuel lines TSFlightlines built for me. Connected them to the valve and placed the valve back onto its support. Ran those lines either to the filter or back to the 90 degree fittings in the fwd fuselage ribs. Then created lines that now run outbd to the wings.
