Right now the guage does not register anything for quite a while during idling and then pegs out during driving. :rolleyes: | | |

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!

The earlier and later are gas (?) filled originally and I think now they use MEK (methyl ethyl ketone) to fill them. Your "CC" would have indeed used an electric guage, GMC part number 1512200.
Take a heater rheostat and hook it up to the wire and then try dialing it up and down and see if you can get the guage to move some. That will isolate the guage portion and let you know if it's the sender or the guage. | | |
