The fuel level sensor on my MEP003A genset failed, preventing me from using the auxilliary fuel input from my bulk diesel storage. I previously thought the problem was caused by a failed solenoid valve, but when I troubleshot the system I determined that the fuel level sensor had failed in the open position. The sensor works by having a magnetic float slide up and down a tube that contains a reed switch. The position of the magnetic float opens and closes the reed switch. Upon removing the four small screws, water poured out. The wiring and reed switch terminals were highly corroded. One wire was separated from the reed switch terminal. I sanded the terminal on the reed switch and cut off a section of wire and tried to re-solder. Unfortunately, I could not get the solder to flow on the terminal of the reed switch. I've now given up and am currently looking for a new sensor. I looked at the GEMS website, but the sensor manufacturer doesn't list this particular sensor as a current product.
