Oil Pressure Gauge Sending Unit Install

[grandam2006]

I have done alot of research for installing the oil pressure sending unit.
So far, the parts that I need are:
3/8 all female T fitting
3/8 hex pipe
3/8 to 1/8 adapter (for autometer)
it was also recommended that I use yellow teflon tape

I am not sure what i use the tape for. I am just curious where the stock sending unit is located, and if oil will come out once the stock unit is removed.
I want to hear any information or advise anyone has about installation.

1. you need teflon tape so the thing wont have a chance to leak.
2. the stock unit is located next to the oil filter.
3. no oil will come out upon removal of the stock unit.
Actually, you dont even need the stock unit as its useless. so you dont even need the t fittings. and no, you wont get an ses light.

If you don't use the stock sender you'll at least need a 90* elbow to clear the starter. That depends on the size of the sender your gauge came with though.

When I installed my oil pressure gauge on the MC years ago, it had the giant can of a sender.

i didnt need an elbow. just screwed the autometer one right into the block

You want to use the teflon tape (or better yet teflon paste) on the threads of your NPT fittings so they don't leak. If you aren't using the stock one, the autometer will screw right into the block, yes.

I recommend keeping the stock one though. It's not really a pressure sensor. It's just a switch that turns on an idiot light when your oil pressure drops below 5psi. I used a T fitting and kept mine just as an extra safety precaution. I thought I read somewhere that if you flipped the car and the oil level and pressure sensors went off that it would shut the engine off as a safety feature, although I can't find anything in the service manual to corroborate that. Anyway that's my take on it.

very few cars have a safety feature looking at oil pressure, most will tun on the light and that is it. cars will start to shut down if you have a bad enough miss fire, or over heat, but will run with no oil till your eng blows, its stupid.

Yeah, I didn't think that sounded right either. Someone on here said it did though. Just goes to show you can't believe everything you read on the internet. Best thing to do is do a little research yourself to back up or disprove the things you read in forums.

We know the engine isnt cut off when that sensor stops reporting because there are enough people who have unplugged them with cars that still run. I personally split mine off on a "T" fitting and left the stock sensor plugged in just for some peace of mind and for the sake of not seeing the oil pressure light in the dash.

I am definitely going to use the T fitting and keep the stock sensor on. Does the teflon tape go on the theads of the oil pressure sending unit?

Goes on the threads of everything you are threading together. Anything that oil will be going through. The sending unit, the stock sensor, the T fitting, the nipple, everything.

i dont have any light related to not having a stock unit, but its personal preference.
