Gas Guage (Page 1/1) Dklosinski NOV 27, 02:12 AM I bought electronic gauges and replaced the fuel sending unit on my 1987 Fiero GT 6 cylinder. The gauge bounces around a lot and is not accurate. Anyone has this problem and fixed it? Thanks! Gall757 NOV 27, 03:38 PM Did it work properly before assembly into the tank? Does the gauge bounce around when the car is not moving? Dklosinski DEC 11, 11:29 AM I installed an electronic gauge and when I installed an electronic gauge the numbers started to bounce around. So then I replaced the fuel sender unit and still the same problem.
