    Fuel Gauge-gctid371787

    Did not put the boat in the water last season, drained the gas out and stored her for the summer. Put about 20-30 gallons in her last week, but no movement on the gas gauge. Put another 10 gallons in her and still no movement. Any ideas on what to do? How can I figure out if the problem is in the tank or the gauge in the instrument panel? Thanks for any insight. Charl

    Try tapping the guage on the dash to see if it moves, If not you probably will need a new sending unit for the tank....

      Thanks, will do. Probably a novice question, but should I need to replace the unit in the tank, will I need to remove the tank to do the job?

        Check your grounds; both the guage and the sending unit.

          Damn, just got back from her. I will check the grounds when I get home tomorrow and let you know.

          Thanks, Charl

            Charl, Had the same problem. I found that the cork floats on the sending units no longer floated! Replaced sending units and all better now.

              The sending unit is a reohstat (sp?) and the fuel guage reads the resistance passed by it. You can put an ohm meter on the sending unit move the arm up and down and see if it is putting out the correct reading (you will have to look up the specs for your unit). There is a way to test the guage as well, again checking the resistance, but the exact method escapes me at the moment.

              If the sending unit and guage check out, and your grounds are good, then I would say the float is shot.

                Thanks for all the help. I will check her out tomorrow when I get home. Again, as a novice mechanic, will I need to remove the tank to replace the floats should they need it? Thanks again, Charl

                  You should be able to change sender/float with out removing tank.

                    Thanks again for the help, and I will check her out tomorrow. Got home too late today to do anything today.
