Jim.

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.
