Going to mechanical oil pressure gauge

I've done several searches, no luck.

2000 Wrangler TJ Sport with 4.0L

Oil pressure gauge maxed out the other day, sending unit undoubtedly the culprit.
Spent several hours today trying to get the wiring clip off of the thing. No luck.
Watched several You Tube videos ... seems simple enough.
Clip side is facing sdwn at the starter and and from what i can tell it appears broken ... will not come off.

Bought new Echlin gauge from Napa and supposedly correct type socket from Autozone.
I know the OEM Mopar part is recommended, but ... they're closed today.

Socket doesn't fit sender, can't get clip off of old sender, and dislike electrical gauges anyway. Took everything back. Going to go with a mechanical gauge and what i need to know is..

... is the OEM sender that is screwed into the block fitted with a 1/8" NPT nipple?
The new Echlin sender had a 1/8" NPT nipple and i have a bunch of new 1/8" brass
NPT fittings that will be perfect.

... and, if i hacksaw the plastic piece off of the sending unit body will oil pour out of the sender if i need to start the motor?

Thanks in advance guys/ladies for any help!!

If you disable the oem set up what will you to about the "check gauges" light coming on and the dinging alarm warning?

Yep, being suspicious of the computer 'knowing' i did not have a sensor plugged in, i finally was able to get the plug to pull off of the connector and drove it. CEL is lit. Sooo, i bit the bullet and went to Chrysler and bought the OEM sensor ...$91.40 ... not cheap. Then went and bought a socket from Autozone that fit the sensor i just purchased. Came home and crawled under the jeep to do a simple swap. The OEM sensor in the block is a different size from the OEM one i just purchased and the socket will not fit it, and there is not enough room between the body and the sensor to operate the socket even if it did fit!! Man, what a PITA!! So, ill just drive it until the end of the week when i have Thursday and Friday off and hack saw the plastic connector off of the old one, find a socket that will fit the one in the block, and use some brass 1/8" pipe fittings to turn the position of the port so that i can use the socket and install the new sensor.

I'm just posting this up so that if anyone needs to change this thing out, they don't end up going down the same road i'm going down.

Note: This Jeep was bought new from the dealer by my wife, a couple of months ago she wanted a truck, so she traded it to me. I know its' history and know there was no PO that may have changed things from factory.

When I changed mine out a while back I was able to get an adjustable wrench on it ...... difficult to make it work but doable.
If the replacement doesn't have a "sealer" on the threads use Teflon tape on them to keep it from seeping.

Thanks Stranger, i was out today looking for a 27mm end wrench and no luck at O'Reillys ... 22mm was the biggest they had. I have an adjustable that i will try when i go to do this thing. The new one has some red coating on the threads and i'm going to use Napa Aircraft black goop on the 1/8" pipe threads.
Thanks again.
