Hi Ron,

Send me a PM with your address information and I will send you a good resistor.

Typically the main problem when the resistor goes bad is you will never register more than 1/4 tank no matter how much fuel you have.

I don't see what photos you are refering to but the stock fuel gauge resistors will read around 90-100 ohms. The 23.3 ohms you have would only get your gauge up to 1/4 tank based on 90 ohms at full, 45 ohms at half and 22.5 ohms at 1/4 tank.

Hope this helps, let me know,

Tom
