D. Story,
This works for me. Run 1/4" Polyurathane Tubing from the discharge from each Facet Transfer Pump through the wall of the instrument panel next to the radio stack on the pilots side up to the day tank (if you use one). The Urathane Tubing is tanslucent; wrap the tubing with electric tape for anti-chafing. Tanks are dry when bubbles appear in the exposed tubing and you get every drop available. I don't have any gauges, the Facet Pumps together do about .67 gal /minute, therefore I have 43 minutes of pumping time. I also have in the same area on the panel a sight gauge off the day tank of the same tubing marked alongside with 1 to 12 gals. Keep the tank level between 5 to 11 gals and you always have good feelings about your fuel situation. Pump out of both wing tanks together so you don't have trim problems. I know, misgivings about flexible tubing in the cockpit area, I replaced all the lines after 5 years of service, still flexible, no discoloration, no rubbed or surface damage areas. Hope this helps..Don Skeele 235/320 650 hrs. (503) 769-2563

I was planning on cutting the panel so that you can see the fuel transfer lines to the header tank. Without doing that, how do you know when the wing tanks are dry?? I doubt you can hear any change in the transfer pumps? Appreciate any practical info, as I would prefer to leave this out of the panel.
Tks,
D. Story
