Real Autometer Oil Gauge - another write up

[babbage]

Ok I finally got this installed. Did some searches and found some old threads that seemed overly complicated. Here is the quick writeup.

• Pull gauge pod down, start at the wings in the back and pull down and forward at same time.
• Disconnect wires and seperate gauge pod from dash.
• Install new oil gauge - switch the blubs and backround if you want.
• Reconnect wires and reinstall gauge pod.
• Go under car - disconnect fake sender connector and cut it off close to the end of the end connector. It's right near the oil filter and quite tiny compared to the real 100 PSI Sender.
• Slide on some heat shrink tubing on to the wire - crimp on small ring terminal add a dab of elec. grease -- heat up to shrink/seal (did have to drill out ring terminal (enlarge) to be bigger first)
• Put teflon tape on the Autometer real sending unit.
• Unthread factory "fake" sending unit. (will loose 1/3 QT oil - let it drain)
• Thread in new Auto Meter 100psi sending unit - where you removed factory fake sender from
• Attach wire with ring terminal onto new sender unit - tighten down.

DONE

Works great - at full temp idle pressure reading is about 24lbs, cold is about 75-80 idle. About 75-90 when hot at WOT.

Kudos to Racer X who sold me his mint old one. How did I live without this before?

You're welcome! Great piece of mind, isn't it!

Missed one step.

Move the gearshift out of PARK (P).

I have both gauges to do this summer. Can you get to the oil sending unit w/o lifting the car? I may need to sweet talk my mechanic with a case of beer to borrow his lift.

You can get at it if you can jack up the left front of the car.

at hot idle i'm only showing about 15-18psi. hmmm

That's about right. Cold I bet your over 100psi.

Cold I'm alomost at 125psi. Hot at idle it's a little under 25psi.

[Got_1]

cold idle is around 85-90. It has never pegged at 100 before

Word of caution. While Teflon tape will go far to preventing leaks, the "real"sensor is a ground seeking device, and the Teflon tape can interfere with the ground. Some nickle anti-seeze generally does not interfere with the ground, and allows a very tight installation which will usually not leak. Something to think about.

Never had an issues with teflon tape on sending units. I suppose too much tape could cause a problem.

[RF Overlord]

Me neither...

[thathotrodlincn]

I did not mean to imply that the Teflon was always a problem. However, I have seen it as a problem in sensitive eituations. It is just one more thing to check when troubleshooting an errant gauge problem.

What # gauge did you use? Did it come with the sending unit? Thanks.

[ctrlraven]

I didn't know it was that simple until as of late. I thought all new wires had to be ran. lol

I think I saw be picking one up here very soon cause I need to get an oil change done before going to the track and I can kill two birds with one stone this way.

Replacement Gauges – Autometer (2 1/16)
Oil Pressure – 4327
Sending unit – 2242
Voltmeter – 4391

You will want to replace both gauges. Although they are close to the originals if they are side by side you will notice the difference.
