I have two 97 GP760 waverunners, and after winter storage neither fuel gauge works properly. On first machine, fuel tank was empty when stored except for approximately two gallons. This sled's gauge works on start up, then sets at 1/4 and the warning buzzer and light start going off. pressing the mode button quiets the buzzer, but the light still blinks.
On second machine, fuel tank was at approximately 1/2 to 3/4 full when stored, and the guage works properly when first started.. but it never comes off full..it is perpetually full (which is kinda nice to think, but not really true! ) Both sleds had "stabil" fuel stabilizer in them for winter. ANY help at all would be appreciated...
