I installed two Sytec one way fuel-valves on top of fuelpumps. Joined with 8 mm fuel hose and a 8 mm T-piece. Outside covered with 15mm fire sleeve. From T-piece a fuelline connect to fuelfilter, with fire sleeve on. Return line from engine connected with pressure regulator to the AN832 bulkhead and firewall. Fire sleeve on all fuel lines.
