Re: Installed '90 GM Factory EFI tank, '72 Blazer Factory gas gauge is pegged past fu

Thanks VetteVet. The ground jumper test is much simpler than the voltage test I suggested. That's the kind of quick-and-easy troubleshooting I need to learn about.

damnyankee36, thanks for your answer to my question as well.

Now we'll wait and see what the OP finds out about the sender...
1972 C20 long-wide. 350/350, Cheyenne Super, wood bed, PS, PB, dual batteries, dual tanks, leaf springs, gauges. No significant rust. No significant paint.
1971 C10 short step. Originally a 250/3ott with no options, now a 350/4L80. I purchased it already restored; only needs about 300 little details fixed.
