Do you race this ?

Tom

 

Yup

 

I can't imagine it's much different than any other car. Get a sending unit that has a provision for the gauge as well as your oil light, and wire it in.
Otherwise on the Torque Pro app, there's a list of the PID's that work with Ford and oil pressure is one of them I believe.

 

Find where the OEM oil sensor is and remove and create a 'T' fitting there to patch oil line in along with the sensor, if enough space of course.

 

If your racing it then I wouldnt do a T , seen to many brass fittings break , I would remove the oil Filter Adapter and drill and tap for a 1/8 NPT and put your oil line in there , thats what I do to get oil to the Turbos

But, isn't it there already something that we can pull a signal from to get the oil pressure? The ECM must know when turn the light on by measuring the pressure somehow.

 

Well, if you look at my earlier reply...

There's a sticky thread with torque pro PID's. You need an OBD2 reader and a smart phone/tablet to attach to it, as well as the Torque Pro app (well worth the charge).
Here's the thread...

Torque PID for Ford Focus

On many older cars, the oil pressure sender just signals a light when it reaches a certain threshold. It didn't tie into OBD2 on my 97 Thunderbird that I'm aware of. On more modern cars it may get it from the ECU, but the light may still use the last ditch bone simple threshold light too. I am not sure on that. But, the ECU should read oil pressure, and if you plug the PID's in, you should be golden.

 

Every racer knows that mechanically derived oil pressure is much more accurate than electronic. Electronic can be as good but lots of money spent to do it.

 

I concur, but for a daily would love to have an approximate than an oil line that could break running thru my dash

 

I've driven copper oil lines to oil pressure gauges on multiple cars for years and never failed a line. How you run it is what stops that. I also ran nylon oil pressure line on bikes to be able to flex in the steering and for years again with zero issues, not even a slight leak.

 

I agree with AMC 49, the mech gauges are more accurate and less problematic. I too used to use copper tubing, I would use fuel line on it as an abrasion wrap in areas where that was a concern. I now use ss braided line with poly tube center. You can pick these up already made with 4an fittings that will connect directly to your gauge and your sender. Make sure not to get the braided line with a rubber inside line, these are for fuel and won't take high temp.
