Has anyone hooked up a Probe oil pressure guage to their MX-3?

aftermarket autometer... you can pick one up for around $50-$60. A small piece of aluminum, a drill and a hole saw you can make a gauge panel that fits in your ash tray spot.

Thats funny, thats what I have planned for mine, I even have the tach in place already

Holy gauges and stuff! Very nice. The reason I asked is because I read that the sending unit hole is metric, and the aftermarket ones are threaded standard. I didn't want to have to use an adapter, if I didn't have to. What did you do, exactly?

I don't know about all gauges, but autometers usually come with everything you need to install them including the sending unit.

Yeah, and what I've read is that the sending units are threaded SAE, while ours are Metric, so I'd need an adaptor.
Is there one that is Metric?
Also, I'm leaning toward a mechanical one that would be set into the wiper cowl.

You don't need an adaptor for the autometer sending unit. It's a graduated thread and goes right into the stock oil pressure sender location. Just don't over tighten, if you tighten it too much you will crack the housing on your oil filter housing. As long as you do it right, you'll never have any leaks or issues.

Cool! Thanks for the info

Forgot to add some teflon tape!

I always use the Teflon on pressurized stuff! Well, except spark plugs, of course.

Usually tapered threads on the sending unit so it should seal without tape. Also the ground for the sending unit is through the threads into the block. So too much tape will actually cause more problems. A little tape won't hurt.

Good to know. I'll thread it in, and see where it stops, and just thread the last little bit, just in case.

I put one on my Xterra and I used adaptors at the sending unit. It was recommended to use an adapter especially when threading into the block (I tapped into where the factory sensor is) as to not cross-thread it. My metric Xterra uses a BSPT thread, but the sending unit uses a NPT thread...the difference is only 1 thread per inch, so you can make them work.

We didn't actually use Teflon tape either but an adhesive designed to do the same thing but it don't isolate the sensor exactly as Davmac said, since it's a 1-wire sensor and needs to ground to the block
