Mine I bought last year shows 1/4 tank when it's dead empty, and full at anything over 1/2 a tank. When I measured it I think it showed 11ohms empty and about 78ohms full which I've been told is close to the factory senders, so I don't know why it's off so far. I was wondering if I could add resistor inline with the ground wire to get it to read closer to correct?

It will show full when you fill the tank, but as soon as you run out little fuel it drops a lot more than it actually should. What i do now is fill up at about 1/4 tank and always find i have about 1/2 tank instead of 1/4. I just live with it now. Yes, it does have the ground strap.
