Real AutoMeter oil gauge

[BAD MERC]

Well last year I jumped on an AutoMeter oil gauge to replace the fake Marauder one. The thread here is extremely well written and after going through the steps it seemed quite straightforward. The car has been stored and covered 4 months so it seems like a good time to do the swap before starting her up. The sending unit was a simple swap and one-wire hookup. The gauge was a drop in replacement for the OE one but the look is similar until the lights come on and then the difference is annoying. The tutorial indicated the gauge face was removable and after some gentle coaxing around the perimeter of the aluminum bezel I was able to gently remove it and the face to swap them into the real gauge. It looks bone stock and performs like a gauge should. Even after 12 years of ownership I am still discovering little changes to improve my Marauder. Thanks to Wes for this fantastic writeup!

Sent from my Pixel using TapatalkThe gauge is a glorified idiot light. There is no sweep of the needle to indicate what pressure the engine is experiencing. It shows pressure if the car has a few pounds up to ?? Many here have replaced their OEM with a real gauge that shows the true pressure when operating. Fairly easy swap if you are somewhat mechanical. I believe the write-up on the how-to is in the FAQ header somewhere. Forget the part number of the real gauge from Autometer, but it is an Ultra ll. Someone will chime in with the part numbers for the gauges. Most replace the volt gauge as well just so they match. Swapping the face of the oil face is a pain.

I have mechanical OP gauge. That's about as real as you can get lol

Me too! Never had to work on the sending unit since I made that swap!

[fastblackmerc]

Consider replace the voltmeter at the same time. When they are illuminated they will both look the same and anyone but a diehard Marauder enthusiast will not know the difference.

[RF Overlord]

Why do you say fake oil guage?Because it IS a fake.

As the others said, it reads approximately in the middle no matter what the actual oil pressure is. Ford does it this way because too many ignorant people complained that their oil pressure was all over the place, not understanding that this is absolutely normal. It will be higher when the RPMs are high and lower when the RPMs are low. It also changes as the oil temperature changes. Rather than keep explaining that to people, Ford just made the gauge read in the middle all the time. It's been that way since at least 1989...possibly earlier but that's the earliest I have direct experience with.

Replacement Gauges – Autometer (2 1/16)
Oil Pressure – P/N 4327 w/ sending unit (P/N 2242)
Voltmeter – P/N 4391

Correct. That's why it says "w/ sending unit (P/N 2242)"

Voltmeter – P/N 4391
Replacement oil sending unit - (P/N 2242)I would have done it as above to be more concise. :P

[eclizotte]

where would I find the stock OIL sender unit to replace?

[justbob]

Right near the oil filter.

isnt there a way to have the org. work?

No

You have to swap out the dummy sender and gauge with both autometer units.
Buy the auto meter volt gauge as well so the face plates match. New autometer gauges aren’t backlit behind the numbers like OEM was. Only the surrounding bezel is.
Or if you’re confident, do a faceplate swap with the old OEM oil pressure gauge onto your new autometer one

If your not careful you will ruin one or both of the gauges.

[BAD MERC]

Anybody afraid to mod their gauges can happily send me their new gauge and gauge pod and I'll do a seamless mod. You pay shipping to and fro and toss in a few beer bucks. Takes about an hour. You install the sending unit and it's done.

Can you show me how to do mine?

[BAD MERC]

Removing the aluminum ring to access the needle/face is more feel and patience than "tell me how". As I did it I realized how easy it would be to damage or destroy the delicate aluminum. I used a small flat screwdriver and gently slowly pried around the back of the bezel until removal was possible. Swap the internal giblets and slip the lense and bezel over the new gauge. You can use a round screwdriver shank to gently roll the edge of the aluminum back onto the gauge body.

[Invective]

If it ain't broke - don't fix it. I didn't even learn of the oil gauge 'peccadillo' until after I perused this board for quite awhile. It makes for interesting conversation.

Absolutely. Although I think there is an old write up in the FAQ section that I followed.
Otherwise I’d be happy to take a drive up

It's not a matter of it's "broke", the gauge is a glorified idiot light. You either have oil pressure or you don't.

The real gauge will tell you about your engine if you know how to read it.

[BAD MERC]

I can think of a few dozen items that "weren't broke" but I replaced or improved them to make a better and more reliable machine. That comment was very Toyota Camry-like.

[the fat bastid]

Just a warning of what happened to me when swapping guts: My screwdriver slipped and starched the ring noticeably. No fixing that. Also, the orange pointer arrow coating is super easy to damage. I ruined my original and thankfully someone sent me an extra one. But I am glad I did the mod. 10/10 would do it again.

[decipha]

back in my supercoupe days it was common practice to slip a ps60 sender in there and remove the in line resistor to make the stock oil pressure gauge read actual oil pressure on the stock gauge cluster in them cars

no chance of doing that with the marauder?

Bump to see if someone has a copy of Wes' write-up that they can upload. Thanks!

This might help, having to use wayback machine for this one as it's not on any active site anymore.

I don't have Wes' even older copy, sorry

Thanks to you guys and time on my hands, I finally got around to installing a real oil pressure gauge.:woohoo::banana2:

You still offering this service?

I can swap out both gauges and make it plug-n-play. Will need you gauge pod & new gauges.

PM me.
