Darren, I have two cheap and easy, flight proiven solutions to offer (tongue in cheek).
I got exactly the same setting: two sealed wing tanks that feed the header tank through a pump. And the same Attention Deficit Disorder too. Once, I got a clear warning that I had forgotten to switch the pump off: fuel was overflowing through the header tank cap, and splashed on the canopy. Is that cheap and easy enough for you? Another time, I heard a funny clicking noise, and ended being convinced that I was losing an engine valve. Scrambled back to the airfield, my eyes glued to the engine gauges... until I figured out that I had forgotten to switch the pump off (again), and that clicking noise was coming from the Facet fuel pump trying to pump air from the wing tanks. Second cheap and easy solution... All the switches on my aircraft have a LED on top of them that is a tell-tale of switch position. Fuel transfer is amber, because it must be monitored. Now, I recently installed a second electric fuel pump, whose purpose is to feed the carb (gravity assist, so to speak). Being short of instrument panel real estate, I took the location of the transfer pump switch, and moved the transfer pump switch lower on the panel. Thik I will manage not to confuse between these two?
