Oil pressure sending unit

5 September 2007
Edmonton, AB, CANADA
Does anyone know the resistance range for the oil sending unit? (for the oil pressure gauge, not the light)
I am trying to source an aviation quality sending unit.
The OEM sending units tend to fail with heat and vibration. SoS has a kit to relocate the sending unit to the firewall (near the coolant sponsion tank/reservoir), but the quality of that sending unit tends to fail over time as well.
If someone knows the resistance range to match the dash gauge, I may be able to source a better quality sending unit that is from the avionics industry.
Oil Pressure Gauge in the instrument cluster wants to see a resistance range of 20-137Ω for a 0-8 bar (116 psi) range.
