You can buy a fitting that screws into the motor, then have the stock sensor screw into the fitting, then have the aftermarket sensor T off and connect your gauge there.

Luckily I have a 95 and I can use the plug right above my oil filter to add a sensor since my stock one is on the top of the motor behind the intake manifold.

You can use the location where you current sender is or use the location behind the intake that later models use.

How are you guys feeding the lines into the passenger compartment?

I know about the grommet on passenger side where computer harness comes through the firewall. Is there a similar grommet on driver side?

I currently have a mechanical oil pressure gauge under the hood. It is connected with a 26" stainless braided brake hose that can be routed under the back of the hood and placed on the windshield when needed.

Question. Does anyone see any safety concern using this brake line for providing pressurized oil to the gauge? Is it likely to fail and spray oil and burn the car to the ground? Its been good for 3 years now but I am thinking of pulling it since it really is not being leveraged.

I use copper tubing to connect my mechanical gauge.

I use the tap above the oil filter on a 95 Vette block for my accumulator


The end of the video shows the area that I use above the oil filter.
