Oil pressure sending unit

[warrenw]

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.
thanks.

Oil Pressure Gauge in the instrument cluster wants to see a resistance range of 20-137Ω for a 0-8 bar (116 psi) range.

Oil Pressure Sending Unit not available

That is a good question. Rarely do the gauges themselves fail. It is usually the senders that fail. And the oil pressure sender is prone due to it being mounted on the block. Notice the SOS sender relocates to the firewall so much less vibration.
