The Fuel Gauge Needle in my '75 1.8 is jumping around when I rev the engine and turn on the wipers and lights, but is stable when I turn on the heater fan, radio, and emergency flashers, and push on the brake.
In 2018, the tank was removed and cleaned, the sender, screen, gasket and fuel lines were all replaced. The last year or 2, this problem began, and has become worse now. I keep the fuel nearly full with non-eth, and this past year the gauge is reading 1/4 +/- and then falls to empty. Sometimes it begins at near full and then drops after minute or two. Routinely I turn the ignition on to heat the coil before starting, and the gauge will drop erratically. I presume to begin by testing the wire connections before pulling the relatively new sender unit. Any other suggestions? Thanks World. See a brief video here: https://youtu.be/NDds6T5DvEo |
