Steve,If you want to it keep simple run the top vent over board and don't worry about fuel loss. I have a vent that is forward facing out the side of the fuselage. I can not see when I am sending fuel over board but I know I have. I usually fly an hour and run the pump 20min to refill. I only forget when I get busy with something else like airspace or radio, In 5 years I have not lost more than 5 gal. I have a indicator light on the panel to know when the pump is runnning. I have a little thought about the tank level switches. I have a light for low level warning off a float switch. It is unreliable. Putting a switch in line to turn off the pump automaticly gives a failure location that you didn't have(shutting the pump off when you need it).Perhaps the most fool proof is the pump with a recirculating line running all the time from one tank to the other Keeping the headeer full until there is no fuel to transfer. Some how I still favor transfering the fuel on demand when I want to and not depending on any automation. Some day when I do it all over I will install a much smaller header tank, larger wing tanks with the recirculaton piping and pump. This would get less fuel in my lap and more room behind the panel, less CG change and still be gravity feed to the engine. About the best solution in my world.More than you asked for but worth every bit of what you paid for it.Good luckJoe Horton

I like the one Joe sent I will look into that one. HOW TO VENT the header tank? My thinking (although might be stupid) is that if I vent the header tank out the top then if while I am transferring fuel from the wing tanks and get distracted and forget to turn off the pump I will notice fuel on the windscreen. I really don't want to put a switch in the tank for a warning light but if that is the way to do it then..... Just looking the the K.I.S.S. system.
