Fuel Level Sensor/Return Line Durability
I have a 2008 Gemini 105MC catamaran that I purchased new, and the fuel tank level indicators on both tanks failed a couple years ago. However, I noticed that the fuel-return line is attached to the top of the fuel level sensor. It seems to me that this may be the problem—fuel spraying down on the level indicator shortens its useful life. All the other Gemini owners that I know also have had the level indicators fail. It is not a huge problem. My tanks are transparent so I can see the fuel level in the tanks. My friends who have black non-transparent tanks use a wooden stick—which can be inserted down the fill hose.
