How to install gauges by Autometer, Part 2 - Mechanical Oil Pressure

[@billboyle7866]

Excellent instructive video! You're "keeping the classic Pontiac engine alive." Well done.

[@FastMonty]

Thanks Bill! Much appreciated!

Hello Fast Monty, love the channel. Especially the ones about gauges. I am looking to install some gauges in my truck. I have been looking at these same gauges you have in this video. These are autometer brand, but are they made in USA? Or are these gauges part of autometer's economy made in China/ Taiwan series ? I really like the look of these. Have they been accurate and reliable? Thanks for any help.

[@FastMonty]

Great question... my guess is these are made in the US. I say that because the digital fuel gauge I upgraded to was NOT cheap, and they changed the bezel to match my current chrome trim rings. Kind of a cool option... had to call them to arrange it for a whopping $20. super impressed with the gauges, and the customer support. Have fun, and thanks for the comment!

Smith's dual water Temp with oil PSI has a 1/8" BSP 10mm on the gauge. I used a braided steel oil feed line with 4AN fittings, 1.25 pitch. To connect to the mbike oil feed either at the oil cooler or on the block I used a dbl banjo bolt and compatible connectors which I sourced from a pneumatics supplier.

[@FastMonty]

Love the ingenuity. I too am running an AN hose now. I detail it in my Digital Fuel Pressure gauge video, for anyone interested. kzbin.info/www/bejne/fWnXp4Kcl7ukppo

[@bobeaseshop9389]

I SAW THAT EDIT!!! You put the ferrel on before the nut (Don't tell anyone but do the same kind of edits). On my 1964 389 the oil fitting pick up is on the oil filter housing. You did a fine job explaining the gauge. You got the big time 80 psi pump! I just went for the 60 on my street Bonnie. Once again nice work Sir. Bobby

[@FastMonty]

Ha! Thanks Bobby... yeah, I put it on backwards, AND it took me two minutes to get the freakin ferrel on, cuz I didn't have my glasses. Had to edit that out. Ha, ha... Yep, got the @butlerperformance 80 lb. Pro Pump in there. Thanks for the comment!

[@rorydaddy]

Please get Rid of the plastic line, they like to split and spray hot oil all over your leg, speaking from experience, Copper Line is the way to go. Great videos

[@FastMonty]

Agreed! The best is using an AN hose... which I switched out for, in this video... kzbin.info/www/bejne/fWnXp4Kcl7ukpposi=zcmeebDV2cR304Y7 Thanks!

[@Dave-ru2qh]

@@rorydaddy thx

[@FastMonty]

@@Dave-ru2qh The ultimate solution is using their AN line... in this video, I upgraded to a stepper motor fuel gauge, and re-used the fuel line as the oil pressure gauge. Should give you some more ideas... kzbin.info/www/bejne/fWnXp4Kcl7ukpposi=Gu5Ez8dTYrIzW_Za Have fun!

[@juancotto6773]

I like your video but my question is which part or area I need to use the yellow tape, I didn't see it here

[@FastMonty]

I used it on the adapter that screws into the block. Hope that helps! If you want to take it to the next level, I recommend using the AN line in my follow up video.. here... kzbin.info/www/bejne/fWnXp4Kcl7ukpposi=49vSp-AFzgtX3kNw Have fun!

[@DHSFEMA]

I wonder if they make a steel braided hose to go around the plastic hose

That yellow tape is for natural gas fittings we use in construction its twice as thick as the white, at least. You dont want a natural gas leak.

@@brucecalhoun1716 Good point, heat fatigue. Thanks!

[@MrSullyE]

Question: You didn't mention and/or cover whether or not you need to 'bleed' the oil pressure gauge line before or after making the connection to the gauge. Is that necessary? I just did this very thing on my 70' Buick GS455... and all went well, but I'm still seeing air gaps in the line coming to the gauge. Would be great to know whether or not 'bleeding' is needed. Thanks.

[@FastMonty]

Great question. The answer is NO. Air gaps are totally normal... even though air is compressible, it still transfers the same pressure reading. Hope that helps! Thanks for the comment!

[@MrSullyE]

@@FastMonty Thank you for the fast reply, I won't mess with it then... keep up the great work. Looking forward to more of your vids. I'll subscribe right now!! 👍👍

[@FastMonty]

@@MrSullyE Awesome! Welcome to the FMG family!

[@marcjonellcruz5522]

Hi. Can I ask when my car is under the sun or extreme temperature I see oil leaking on the glass of my auto meter. May I know how to fix it?

[@FastMonty]

That's not normal. I'd recommend getting a new gauge. Or, send it back to Autometer for repair. Good luck!

[@innovruptly1769]

Now, oil pressure in a mechanical gauge depends on the oil reaching the gauge, not so? Is it necessary to prevent the oil from draining from the capillary tube or does it self prime?

[@FastMonty]

Actually, NO. Oil does not have to reach the gauge. As you can probably see air gaps in clear tubing... you have to keep in mind that air can be pressurized, and transfer pressure to the gauge. So, there's no need to bleed those lines, or worry about oil draining away from the gauge. Thanks for the comment!

[@aliothman7816]

How long your flexible hose can last? What is the lube oil temperature?

[@FastMonty]

Good question... I have no idea how long that tube should last. I'm sure it depends on environmental conditions, heat cycling, etc... I would recommend using their Braided Steel line, which I ended up using in this video... check it out. kzbin.info/www/bejne/fWnXp4Kcl7ukpposi=jBcFqrlb8STLyW1S

[@banks412]

I’ve noticed in my mechanical oil pressure gauge’s capillary line that there appears to be oil throughout the line. Is that normal? I’m not 100% sure the gauge is working. It was installed in my 65 mustang by a previous owner. Any advice would be great - thanks! Great video on the install…

[@FastMonty]

Yup, oil in the tube is normal. Thanks for the comment!

[@swallag]

Surely I'm a noob, but I have a silly question. So basically, with this mechanical OP gauge, there will be oil passing thru the hose? Or the oil will push the air inside the hose that goes to the gauge, hence the reading

[@FastMonty]

Good question... it's a little of both. If you're using the clear capillary tube you'll see oil AND air in it. Which is fine, air pressurizes too... and will translate the pressure to the gauge. FYI, you always have to keep an eye on the plastic tubes condition throughout it's life. OR, upgrade to an AN line, which I did in this video... kzbin.info/www/bejne/fWnXp4Kcl7ukppo Have fun!

[@swallag]

​@@FastMonty thanks for solving my doubt. well, it's quite creepy the idea to have hot oil passing in the cabin, maybe I'll go for and electronic gauge....

[@FastMonty]

@swallag7069 yeah, kind of disturbing... check out the video I sent. I used an AN line on the oil pressure gauge. That ain't gonna leak. Have fun!

[@justmedontknowdoyou7860]

It's called a Compression Fitting Nut,,the 'BELL" looking thing is called Ferrell..Just an FYI everyone...DO NOT USE THAT plastic tubing get some 1/8" copper tubing....As you can over tighten the nut an cut it and over time it will become brittle..Think a minute how much of a mess that would be in side. High pressure and "HOT" oil

[@FastMonty]

Thanks, pretty sure I said that... and totally agree. But, the ultimate line is their AN line kit, which I used in the upgrade to this video, here; kzbin.info/www/bejne/fWnXp4Kcl7ukppo Thanks again!

[@ElCalin]

Thanks for your great videos. Do I have to purge the oil line? I see air bubbles and I'm not sure that's going to affect the accuracy of the gauge, Thanks for your help.

[@FastMonty]

You're welcome, and good question. The air bubbles are normal and does not affect the final pressure reading. Thanks for the comment!

[@ElCalin]

@@FastMonty Thank you very much for your kind help, I'm proceeding to install my gauge, this time replacing the provided nylon hose with Stainless steel braided hose. Happy Holidays Sir

[@FastMonty]

@@ElCalin Nice! Let me know how it works out... I might do the same.

[@ElCalin]

@@FastMonty Hi, it work pretty good actually, I think I purge the line accidentally, this accident can be replicated to purge the bubbles out. What append was the line was not tight enough at the gauge, after running the engine for a few minutes I noticed a little drop of oil oozing out so tightening a little more was necessary to stop the leak, at this point I think the air was totally or partially purged. For the initial test I completely cover the carpet with blankets and rugs and wrapped the line around the gauge nut with a paper towel in case of leaks, I have a high oil pressure problem so I used a $14 copper line kit from Auto Zone so I can not tell if there is air still trapped in the line but the gauge seems to be working fine, Thanks for your help.

[@ElCalin]

@@FastMonty I couldn't find the proper fittings to use the Stainless line so I replaced it with copper line

[@doug595959]

copper is the only way to go

[@FastMonty]

Agreed. I went one more level up and used their Braided AN Line kit. It won't break, or leak. Love it!

[@JoeVizethum]

cool and helpful video ! I'll be installing exactly the same oil pressure gauge now - how about the plastic hose for 40/50 psi pressure in my case ? I already have a n Autometer vacuum gauge installed with the same plastic tube which works fine for this application, but for oil pressure ? May be a braided steel hose kit might be more secure over time ? Thanks for your advise !

[@FastMonty]

Thanks Joe! So far my plastic line is working fine. But, the alternative is using their Copper line. Just be careful not to bend it too much, as it'll break, and/or get brittle. Have fun!

[@JoeVizethum]

@@FastMonty I now have installed my Autometer Mechanical Oil Pressure Gauge which has air bubbles in the nylon line and also shows a significantly higher pressure compared with the original electrical gauge. Warm engine at idle 800 rpm: Electrical - ab. 16 psi, mechanical - ab 33 psi. At 2000 rpm: Electrical - ab. 40 psi, mechanical - ab. 60 psi. Do I have an issue because of the air bubbles or something else ? Thanks !

[@FastMonty]

@@JoeVizethum That's great! Air bubbles are normal. Your Mechanical gauge is telling you the truth, that's fantastic oil pressure. Great job!

[@JoeVizethum]

@@FastMonty many thanks, Monty - you're my gauge expert now !

[@FastMonty]

@@JoeVizethum Everyone needs one of those... I think? Ha, ha...

[@johnmilner7603]

I use liquid teflon on the threads and it works. Never liked tape. I’ve had my tylon oil pressure line installled since 1981 with no issues. But maybe it was better quality back then that came with my Stewart Warner gauges.

[@FastMonty]

Thanks John, yeah, I typically do too... maybe I didn't put enough on this time? The Oil resistant PTFE tape worked great. Thanks for the comment!

[@packnplay]

I might have missed it but how tight are you going with the connections on the gauge end?

[@FastMonty]

So, there are two threads to be concerned with... the 1/8 NPT fitting has oil resistance PTFE tape on it, which is tight. Like you would for any plumbing job. :) The fitting that has the plastic tube/collet, is not quite as tight, because you can damage the plastic tube. Sorry, I wish I could give you a torque to use... but, I don't have such a wrench. :) Let me know if that makes sense, or not. Thanks!

[@gregschultz2029]

Good Job Fast Ponty , I am running electrical gauges, for very tight clearance issues ,But I would rather run mechanical , I would go copper line with a rubber hose for sheathing ,If you have clearance ,The Old Deal ,If It’s Worth Doing ,It’s Worth Overdoing !!! Thank You !!!

[@FastMonty]

Thanks Greg, and great point! Over do it, where you can. Thanks again!

[@WillyDabney]

What do you do when you can't screw oil pressure sensor in

[@FastMonty]

I'm not sure, can you explain in more detail?

[@mikeburnett7028]

When you pull the distributor, can you detail how you set the timing to correspond with the FiTech? Is your distributor controlled by the FiTech. Having a little problem with timing mine.

[@FastMonty]

Good question Mike... I do NOT have the timing controlled version. BUT, I will be upgrading to that one in a few months, so you'll have to hang tight for that video. Sorry I'm of no help, right now. :)

[@hughphillips67Mustang]

Do you have to use sealant since it is brass fittings?

[@FastMonty]

You mean on the back of the gauge? I did end up using Yellow PTFE tape. hope that helps! (I eventually changed to an AN line, which does not need tape) Here's that video... kzbin.info/www/bejne/fWnXp4Kcl7ukppo

[@hughphillips67Mustang]

@FastMonty I have never installed tripple guages before. I'm a beginner. Even though I have restored classic Mustangs for 40+ years. I've always been old school. So, I got a set of Bocsh mechanical guages for my 1967 Mustang. Stock 289. Hooked everything up per instructures. Then realized, the instructions never stated anything about putting any type of sealant on any of the fittings. All the fitting are brass. My temp went into the plug at the thermostat housing. And the oil pressure went onto the left side of the block where the original oil switch went. But I didn't put anything on the threads. Should I take it all back apart and put something on them? All I have is white Teflon tape. And RTV sealant.

[@FastMonty]

Ohhh the sending units. Yes, definitely remove and add the liquid thread sealant. It's just a security measure, you never know if the mating thread was made in China, or not. ha, ha... Do not use PTFE tape on those threads, because you need a current path. Have fun! @@hughphillips67Mustang

[@brucecalhoun1716]

I NEVER run plastic line for OP. After having one break and spray my legs.....Copper line for me.

[@FastMonty]

Good point Bruce... I'll be switching to Copper soon. Thanks!

[@edgardorosario424]

Thank lider✌

[@FastMonty]

Welcome

[@calthorp]

I don't like the mechanical gauge as I had that plastic tube work harden or get brittle after some years & it snapped off at the block. A large mess was the result just lucky I noticed before it pumped all the oil out.

[@FastMonty]

Ohhh, glad you caught that in time... the mechanical gauge is the best at determining real life pressure, so we're not reliant on electricity. That said, I totally agree that the flimsy little plastic line should never be used. Either use a copper line, or what I eventually switched to, which is a -03 Stainless Steel Braided hose. Which I show off in this video... kzbin.info/www/bejne/fWnXp4Kcl7ukppo I hope that gives you some ideas. Thanks for the comment!

[@calthorp]

@@FastMonty Thanks for the reply, think copper could do the same. The Braided hose should be good for a very long time though.

[@FastMonty]

@@calthorp Yep, copper is better than the plastic, for sure... but, can break if bent too much. AN is the best, for sure. Have fun!

[@tucka1234]

What sort of thread sealant did you use

[@FastMonty]

Good question... on the machined threads I used Yellow PTFE tape. (It's for petroleum products) Please keep in mind, I don't like that capillary tube, in a later video I switched it out for the Autometer -04 AN stainless steel braided hose.

I have a 350 Chev small block out of a 1975 truck that I have in my 77 Corvette that reads 80 pounds psi after putting in a new sending unit… I thought that maybe that was too high but after watching yours go to 80 maybe not . Is that normal as I thought it would probably land in the 50 to 55 range? Thank you

[@FastMonty]

@@chuckmackenzie7735 Yeah, depends on the pump. I have a 80 psi pump. Standard is 60, for my engine. Keep in mind, cold pressure is going to be higher. When warm, your engine will most likely be around 20 psi, at idle. At 2500 rpm, you need to see the 50 to 60 range. This is assuming you have the correct sending unit too. Fun stuff.
