lelshaddai Posted October 12, 2012 Report Share Posted October 12, 2012 I have been searching for an answer. I have a problem with my fuel gauge (53 Plymouth, Suburban) I replaced the sending unit with one out of a 54. It needed to be longer. I fixed that. The sender seems to work as the test bulb gets brighter and dimmer when moved. I have checked the ground to make sure it is secure. However the gauge jumps all over the place. The tank is 1/4 right now and it reads full, then jumps to E, then back to F. It does not register. Is this a faulty gauge? Quote Link to comment Share on other sites More sharing options...
