I have an old Stewart Warner mechanical oil temperature gauge. The lead for the sending unit is a hard wire /cable but is too short since this is going in a Corvair and the gauge is designed for a front engine.

Do any of you know if there is a way to splice in an ‘extension’ so I could run the gauge all the way to the dash? The connector / cable looks the same as a mechanical water temperature gauge.

Thanks

No.
What you have is essentially a pressure gauge hooked up to a sealed tube. The fluid inside the 'bulb" expands when it gets hot, and the gauge reads the pressure, but is calibrated in degrees.

Mount it on the shelf panel, facing forward, and read it in the rear view mirror. Problem solved. It'll read backwards of course, but you'll get used to it.

Thank you for the feedback, I will probably install it in the center console. It looks like I have enough wire to make it that far.
