Something new to play with
Two days ago I wrote how I seldom consult my reference books for info on our boat systems. Yesterday, I decided to give them another chance.
Nigel Calder’s book Marine Diesel Engines includes the above illustration of a fuel tank float sensor. After reading what he had to say about the devices, and chatting with our friend Wiley, I decided to try to remove ours from the tank to see if there were any obvious problems with it. Unfortunately, after a slightly tricky time of getting it out of the small hole, I found no obvious issues. In fact, the float appears fine, the arm appears to move freely and the resistance when checked on my ohm meter varies as the arm is moved. That was as far as I got with it yesterday. Today I’m going to check the gauge itself and if necessary, swap the sensor into the starboard tank to see if it gives the same false readings.
