Guys, I took an original AC sender out of a 56 235 car engine I have laying around in the barn. I set my ohm meter on the 2k scale.At room temperature the sender read .710 as measured between the wire terminal and the sender body.I then held the sender tip in boiling water for one minute. The reading was .145 ,still on the 2k ohm scale.If you want to try it in your engine I will mail it out to one of you guys, just as long as I get it back eventually.Its the larger thred style,looks like 1/2 inch pipe thread.
Oh yeah, do Chevys use a voltage stablizer to control the voltage to the guages? Its a small gizmo somewhere on the back of the dash.VWnate probably knows what they are.
