Although I could find no one from this site who had installed the Sensatank 100 Marine tank monitoring system, I did the project this May. I am completely happy with the unit. It does what it says it will do and the installation was straight forward. I bought it through WM. It beats having to drill holes into tanks. The secret to applying the pad sensors is to use isopropyl alcohol (as they suggest) NOT rubbing alcohol, which contains lanolin and does not allow proper adhesion of the self- sticking pads. I will gladly provide more info. I installed it on my C320, but it should work on most systems.
