Lou1119,

I thought someone who really knows what they're talking about on the topic might have responded by now. However, in case it is of any help, the following is a post from another site from someone who seemed confident in their knowledge on the matter and at least may offer some thoughts for your testing on the 1/4 tank read issue.

Needle pegs full or past full – Break in the fuel sender wire (Tan) or tank’s ground wire is disconnected

Needle pegs empty or past empty – Break in the Gauge’s ground connection (under the dash)

Needle’s stuck in one place – Break in the Gauge’s 12v supply

Needle only moves to ¼ full – The resistor on the rear of the gauge is bad or has ground out to the side of the gauge housing.

Best of luck. Brent
