I hav e a 1992 Jersey boat with twin 6V53 Detroits and have been experiencing a fuel guage problem lately. I have separate fuel tanks for each engine, but only one fuel guage. A toggle switch flips to the port to read port tank and to starboard to read starboard tank. As of now the guage just twitches a fraction from empty on either position of the toggle. I replaced the toggle switch and that was not it. I checked voltage at the guage and do have about 6- 8 volts there. I was not going to put 12 volts to the guage as it probably should not have 12 volts to it. What I can not comprehend was when I last filled up both tanks the guage read fine for both tanks.
Ran the boat a few days ago and the guage just is twitching agin by the empty mark. I know there has to be over 300 gallons in the boat but it will not read. I did check the grounds on both tanks and clean them up and that did not work. As a last resort I am thinking it must be the guage being intermittent. I am asuming that the guage must match up with the 2 sending units brand wise. I would appreciate any help regarding this problem.
