Slight Mod to Oil Pressure Sending Unit On '00 XJ
So I have been meaning to check my oil pressure with a mechanical gauge. This is the tool I have to do so.
So as some of you know I always come up with these dumb ideas.
This involves putting in a "T" fitting to make is so I can put the mechanical gauge on the Jeep anytime I want without having to remove the sending unit. I figure I have to pull the sending unit to check the pressure so why not set this up when I do so.
I believe everything to be 1/8" pipe thread. I believe the gauge itself to also be 1/8" pipe thread.
So I am thinking using something like this:
https://www.zoro.com/parker-street-t...-2/i/G4582103/
Something like this to plug the opening in the "T" where the mechanical gauge would go when not in use.
https://www.zoro.com/zoro-select-hex...yABEgL4h_D_BwE
Been poking around and have seen where guys have done similar stuff to run both the gauge in the cluster and a mechanical one at the same time.
I don't see a problem with this.
Am I missing something?

Yea they come in all sizes. I usually pick up what I need from the local Ace or The* Home Depot. If I need odd stuff I'll go to the Parker distributor but that can get expensive quick.

We sell all sorts of fittings at the store so I figure I can find what I need there. Especially since thinking what I need is pretty basic. Hoping we have an oil sending unit in stock for my Jeep so I can double check the size. But pretty sure it is 1/8".

how often do you really plan on checking it with a mechanical gauge? i checked mine when i bought it, 135k miles ago. it will let you know when the pressure is low, just give a listen.

You would think but having read a few 0331 head threads nobody really mentions that they hear everything clacking away in there. Just little or no oil pressure at a hot idle. Frankly if I could set this up probably check at least once a year just because I can without much fuss.

So I rigged up around like the oil pressure sender like I wanted to and checked it with my OTC tester.
So with both the cluster and the mechanical gauge hooked up on start up the mechanical jumped to 70 but settled down to 60 pretty quick. Cluster went to 60 but settled at 52 pretty quick.
For awhile the mechanical was reading a little higher then the cluster gauge. But as the Jeep got hotter then it started reading a lower.
The sensor in there now has been in there for about 3 years. It is the Echlin one at Napa. For the longest time it would read 22ish at a very hot idle. But in the last 6 months I noticed it reading just a little higher.
Anyway to bottom line it. I let the Jeep idle for about an 75 minutes in the driveway. Pressure on the mechanical gauge read about 22. I am OK with that.
Finding the fittings I use for the set up proved to be a little harder then I thought it would be. I figured we would have them at the store but no. Struck out at an Auto Zone and Advance too. Even Home Depot did not have what I wanted. Ended up finding them at O'reilly's.
