Ran 3/8 in Al line from the gasolator, to a bulkhead at the rear of the gear channel, from there to the bulkhead in the seat support to the AndAir selector valve in the center console. Also rand 3/8 in. Al tubing from the tanks to the bulkhead in the rear spar. I will only need 6 in. for flexible line between the bulkhead in the rear spar to the fittings on the fuselage.
