Hello, I read the Sticky on Fuel gauge and sender operation and diagnosis , but had a question or didn't understand since it was talking about the gauge going to empty when grounded. My fuel gauge reads empty, when I ground the Tan wire to trunk it goes to Full, then back to empty when reconnected to the gauge. Is it safe to say my gauge is fine and this is either a grounding or sender issue? Why does mine go to Full when grounded instead of Empty like Jason said? Thanks.
