Oil Pressure Gage and Sending Unit Revisited

Interesting that the 1985 AMC Jeep specification at 60 psi is 13 to 15 ohms, or 14 plus minus 1 ohm.
The 10 psi reading is 36.5 plus minus 1.5 ohms.
It seems like the even if the reisstance is uneven it should not be ranging more than 2 ohms at 40 psi.

I don't think its the same sender but the gages are same type.
