Gas Gauge Problem

[Mag]

I double checked and it is grounded good at tank. I have been checking on replacing the gauge. I was told that the gauge is determined by the ohms from sending unit and they varied from 0 to 90 on some and 30 to 240, etc. on others. I have checked online to find out how many ohms Airtex E3637S sends out, but have found nothing. I called several auto parts stores and they cannot give me any info. Guess I will call Airtex company and ask them after the holiday.

Thank you very much for your help.
