OK, I have read many threads and posts here, possibly too many, and I am being left confused. There is a lot of info, some of which is contradictory.

What size is the factory oil pressure switch's threads? 1/8" ? 3/8” ? Some metric value? I have read several posts of others asking this question, but never saw an answer.

I believe I need some kind of "T", like the one shown in the pic below, that I am borrowing from one of the threads. This will allow the original factory oil pressure switch and the new oil pressure transducer to share the same attachment point.



Where can I get such a "T"? Does anyone have a PepBoys or AutoZone part number?

What is it made of, brass? Aluminum? Something else? I am reading the "cons" for both.

What size is it?

Should it be ridge or flexible?

Any other suggestions would be appreciated!

 

Good question, I was interested in installing one myself. I hope you get a reply.

The "T" is not a T. It is a Sending Unit Adapter.
It is sold by Craven Speed. Refer to link.
It will allow you to mount a oil pressure sending unit AND a oil temperture sending unit.

 

If you have a car with the "Chrono Kit", you get an oil pressure gauge and oil temperature gauge, and still have the low oil pressure idiot light. Where do all of the factory senders go? Does the factory use various adapters on a single threaded hole, are are there additional sender mounting locations that go unused on cars without the Chrono Kit (and therefore may be available for aftermarket gauges)?

 

Can't really ansewer that offhand.
Suggest you look at Bentley manual for that.

 

I already have the Chrono Kit, but if there are in fact unused sender holes from the factory, I just thought it might be another option for those looking to add aftermarket gauges.

 

Very interesting suggestion. Thanks for mentioning it.

Now if someone just knew the answer.

 

The adapter you need is shown on the Craven speed link as shown above. Just give them a call. You will have to disconnect the yellow clip thingy and unscrew the plug it is attached to (prevents the wire from being broken), then screw the new adapter into it's place. Place the original screw that you removed previously into the large (rear hole) of the new oil pressure adapter. The remaining 1/8 npt hole is for the sending unit that comes with the gauge you are using. I would use teflon tape on the threads. Models after year 06 use a different type of adapter but basically the same procedure is used. It looks like the pix already has an adapter installed.

 

Mounting the oil pressure sender and the idiot light sensor in the stock location is a really tight fit. Not much room under the oil filter. I did a remote mount for both senders. Much easier to thread everything up and attach your wires. Did this 8 months ago and "no leaks"

 

What did you use for the "remote" tubing?

 

High Pressure steel braided line with 3/8" fittings on each end. You don't need anything quite this tough but I had this laying around my shop so I used it. Any line that is rated for ~100 psi will work since the oil pressure runs up to ~60 psi or so.

 

If you use the adapter and don't use the remote idea, can an electronic sender work? I’m going to be installing the nexus gauge.

 

I haven't done this yet, but I believe the answer is "yes". Using the remote hose or tube, is only to allow you to put the electronic sender a bit further away. That helps only because otherwise, it is a pretty cramped area to get your hands and tools into. Cramped, though, does not mean impossible.

 

I just installed an oil pressure gauge this past weekend. I bought the adapter from Cravenspeed. It was easy to install. I have the electronic sender coming off the adapter and then ran the wire into the cabin following my boost lines and water temp sensor lines.
