How does the cluster's oil pressure gauge work?

[TorontoGT]

What I mean is, how does the oil pressure gauge work? Is it mechanical? Right now my oil pressure gauge is dead but the previous owner installed an AutoMeter oil pressure gauge that works fine. It is a mechanical gauge with an oil line running to it. What I'm wondering is if he took this hose from the cluster and hooked it up to the AutoMeter gauge.

Cheers, and Happy Holidays

No the stock sending unit is more like a switch. it is electric not mechanical. If the one you have is mechanical the previous owner istalled a line to the gauge, its not factory.

+1 a stock sending unit is exactly an on/off switch and does not give and actual reading of pressure, just that it is seeing pressure.

Stock sending unit is right above the oil filter.

More than likely, the original owner just unscrewed the stock sender and installed the autometer's sender in it's place.

A TEE will give you two ports so you can install both, but more then likely you might need to buy a new OEM sender since yours might be MIA.

The plug is a simple 1 wire push on type of plug that should be hanging in the area

More than likely he removed the stock sending unit and is taking pressure from the same port directly on the right side of the timing cover you should see the line

Thanks guys!, that clears it up.

There's a brass coloured fitting right near the oil filter that has the line coming off of it that runs to the gauge. Like you guys said he must have changed it to the Autometer one.
