All lines are breaded Stainless steel and a mixture of Russell and Aeroquip and AN fittings. Since the switching valve I'm using didn't have AN attachments it complicated things a little. I also installed 2 fuel filters between each tank and the switching valve. I zip tied them onto the side of the fuel pumps so they can be inspected from inside the rear cockpit. I still need two bulkhead fittings that were ordered from Aircraft Spruce to penetrate the Firewall.
