> I'm disappointed they're not using solid state devices. Reed relays are not all that reliable. I had a scuba light that used a reed switch. It didn't last too long, but then I held a strong magnet to it a few times which might have had something to do with it. (typical me) I would really like to have a fuel sender that would give a warning before the tank was overfilled -- especially considering all the points for leaks. Do you have any ideas for a better design? (Not that any of us would get around to building one.) I was thinking about using a capacitance meter but that might not be reliable enough. Another idea was to use a long coil of wire where the turns get progressively tighter at one end. Then the float would have a metal sleeve in it that would linearly change the inductance of the coil based on the float's position. Or would the presence of fuel alone change inductance? Or is this a topic more suitable for the DMC Electrics Yahoogroup? :-) Another idea is to use an ultrasonic device for detecting the fuel level like is used in cryogenic nitrogen bottles.
