Where are your pumps located? Mine are on the floor just past the Andair valve. Dual filters are on the firewall. My pumps are under the back seats (Cozy IV) in compartments sealed off from the cockpit, but with a drain to the gear well. The filters are in the gear well. I have no fuel valve, just emergency shut off ball valves - push-pull cables from the armrest pockets. The return is switched by a solenoid on the firewall. The advantage of this system is total redundancy and very short fuel lines. It's only 8 inches (downhill) from the tank to the pump, and the return is also very short. The downside is pilot workload / monitoring that the return is going to the correct tank. I may solve this by adding a facet transfer pump a la Tracy and running off one tank during normal operations.
