I don't have an automatic fuel transfer system and must transfer fuel manually from the wings to header on my early 235. Early on, I realized that I needed something to alert me to the fact that the tank was full and starting to dump fuel overbaord via the vent line - get busy in the clag and all of a sudden I'd smell gas and "Oh Crap"! - remember that dang switch.

So I built an electronic sensor to detect the onset of fuel flow in the header overflow that flashes a red warning light on the panel. I believe the system design is in the LML archives, but I'm not sure. If you're interested, and can't find the thing there, email me off-line and I'll try to dig it up for you. It has a sensitivity adjust and I've set mine to flash the light at the first few drops - which means the header is full to the max.

I know there are many other ways to handle fuel in our LNC2's but I suscribe to the KISS principle. I've been flying it that way since 94 and works fine for me.
