Does anyone know if the reproduction 80# sending unit sold be Dennis Carpenter has internal workings like the original or is it a variable resister like the GM ones? http://dennis-carpenter.com/oil-pressure-sending-unit-80-lb/p/41A-9278/?tab=cars

Don't know, but I do know that it shows the oil pressure on my '51 8RT to be 35 psi rather than 50 psi. I have checked the pressure with a mechanical gage, and it is actually 50 psi. My nos gage that gave up the ghost always indicated 50 psi. A second sending unit from Carpenter gave the same results. Carpenter's ad says it's exactly like the original, whatever that means.

Thanks ,Dan. I have a couple and need to get out in the garage to test them. I was asking the question to help a guy on another Forum. He bought the NAPA replacement and I am pretty sure that it is the variable resister type as it does not show the correct pressure. Thanks for your information, Richard. Now I will not recommend them.
