Guest BigNorm Posted March 1, 2016 Share Posted March 1, 2016 hi, i have to set up an aftermarket fuel guage and i have to program the ohm readings for the fuel guage.did i read somewhere correctly that a 63 riv is a 0-45ohm fuel sender? if so, does it measure 45ohms when its full or empty? cheers Link to comment Share on other sites More sharing options...
telriv Posted March 1, 2016 Share Posted March 1, 2016 45 is the correct number. As the level goes down the ohms go up I believe. Link to comment Share on other sites More sharing options...
RivNut Posted March 1, 2016 Share Posted March 1, 2016 Just Google GM sending unit ohms. You'll get a bunch of hits on 0 - 30, 0 - 45, and 0 -90. They all state that you're at 0 when empty. Link to comment Share on other sites More sharing options...
