I'm stumped.

I bought a Longacre steel braided oil line to replace the plastic tubing on my current aftermarket gauge.

For the life of me, I cannot find an adapter between the two. The back of the gauge has a 1/16" male compression fitting. (that's what the consensus is between Lowe's, Home Depot, Oreillys, and Advance Auto)

The end of the steel line is a larger (I believe 1/4") female compression fitting.

Where would I even begin to look for an adapter?

 

Well I can tell you for sure that is not a compression fitting…, unless you have an npt to compression fitting adaptor screwed into it… the package that you linked to doesn’t show a compression fitting at all, looks like NPT on both ends… probably ¼ or 1/8” npt (1/8” npt is about 3/8” in diameter), and if the gauge is smaller I’m getting that it’s an 1/8 or 1/16” npt. What brand of gauge is it?

if you’re trying to connect ¼ to 1/8” NPT, well you should be able to get an adaptor at the hardware store, if it’s 1/8” to 1/16” npt go to a proper speed shop and NOS makes an adaptor fitting, or if you just buy any normal gauge line (like the autometer braided steel line) it comes with most of the adaptors that you could usually need in the package with the line (comes in 3, 4 and 6’ lengths)

FWIW, I’m hoping that you’re not running that inside your car.

 

Actually, I’ll take that back… the back of the gauge might have a compression fitting, and nothing in that picture is a compression fitting but at the bottom is says that that is a picture of a different PN.

Again, what gauge or some pictures might help, but for the most part what I’ve already said should answer the question once you figure out what you have… autometer has adaptors for just about everything in this range and what you can’t find there you can usually find in NOS’s list of oddball adaptors.

 

It is an oil gauge, not a fuel gauge. Why should he not run it in his car?

 

 

The first two adapters came w/ the steel line. The different part number (pictured) is for the 60" line, mine is a 48". BUT, sorry I didn't see this sooner, the package says "GAUGE LINE 48 #4 w/#4 AN ENDS" I'm guessing the adapters go from AN to pipe.

The second pair of adapters came w/ the gauge (I think). It's and iequus gauge from O'reilly. The plastic line also came w/ the gauge.

Fitting on the back of the gauge measures .312 OD

This is an oil pressure gauge, I don't see why not to run it inside the car. The whole reason for trying to get this steel line to work is because I don't trust the plastic one.

I'm going to try find a speed shop locally and check out the NOS stuff.

 

do you want hot, say maybe 250*F oil filing the inside of the car, maybe running down your leg while you're trying to safely get the car stopped?

 

My $.02: if you intend to mount it inside then just return it and the braided line and get en electronic gauge.

Looking at the fittings with the gauge (last pic) it looks like you’ve got what you need to use it in a Honda, but not in your gm., actually, I’m not exactly sure what the second fitting is there… the end facing up is a compression fitting, the bottom could be NPT, compression, BSP…, but it does look to be a larger fitting that might be getting you to the braided size. (if someone out there has any clue, why the hell do Hondas use BSP fittings rather then metric fittings?)

That’s probably an 1/8” compression fitting on the back of the gauge, you should be able to get a compression to npt adaptor at a good hardware store or speed shop and from there it should be no big deal to step up or down in NPT size or to AN fittings. That being said this whole hassle could be avoided if you went with a gauge that wasn’t packaged targeted at the import market and/or with a braded line that wasn’t intended for a circle track application… and again, if it was me I’d just get an electronic one.

 

Now you are splitting hairs, I guess we better watch out for that 250* coolant gushing out of our heatercore in that front end crash... I might just mount that outside now that you mention it.

He is mounting a SS braided line, not nylon. I do not see a cause for concern. Hot oil will not kill you. Fuel on the other hand.....

 

either way man do what you want. its your car put it in the car put it on the cowll. either way you get to see what your oil pressure is. me myself I like the electric ones, but I would think that mechanical ones are very accurate. I have electric gauges and one mechanical water temp gauge. like I said its your car do what you want.

 

Coolant usually stays about 50-100* cooler then oil once at operating temps, and there is a reason why the heater core is mounted on the passenger side where a hot leak will not prevent you from driving the car. Both oil and gas only burn if they are atomized/vaporized or wicked into something, so they will pretty much only burn under the same conditions (admittedly gas burns easier), and oil will by far be the hardest to clean up of the three.

It sounds like you want to look good with the braided line, this is all it takes(ABOVE LINK).
Cover this kit wth the stainless for looks????

As for running an Oil Line into the inside of your car, you would be telling almost all sanctioned Racing ,Street or Cruiser that they are "IDIOTS".
Im sorry, I dont mean to be rude but, using nylon tubing isnt a smart choice, but copper, or braided, YOU HAVE TO BE KIDDING!!!!!

ITS NOT GASOLINE
Just so you know I have installed more mechanical gauges 100 to 1 compared to electrical. DO YOU WANT THE TRUTH OR WHAT YOUR ELECTRIC SYSTEM DELIVERS TO THE ELECTRIC GAUGE??????????????????????????????

I have witnessed 10 pounds of oil pressure difference, 20 DEGREES TEMP IN COOLANT???

I want the truth and mechanical is the only way. MY 2 cents!

One more reason that I like electric sending units...

 

Simply put, I never even knew about that kit. I'm not going for looks, just going for the "I don't want plastic/nylon whatever it is"

FWIW, the gauge is NOT a 1/8 NPT. That's the first thing everyone that I've taken this to has said. The more I think about it, I bet it's a straight thread seeing as how a compression nut screws onto it.

A few other things that irked me. The "normal gauge line (like the autometer braided steel line" is the same thing as the Longacre "circle track" line. I would have had the same problem. I'm also really curious as to how this gauge is directed to the import market?!? How is this any different that an Autometer gauge?

On that note, just for my own personal knowledge, about what size is the fitting on the back of a higher quality mechanical gauge and what kind of line does it have?

And to those that warn of something happening to the copper or steel line, thanks for your concern, I'll take my chances that something else will break long before the metal line.

FINALLY, for the time being at least, I order that copper line because that should fit right in. Thanks Rotton

 

I think I said that it’s an 1/8” compression fitting… the seal is not made on the threads but where the shell presses the ferule that you put over the line into the recess in the back of the fitting…

Import… the BSP fittings/adaptors… the only common cars that use BSP fittings are Hondas (which makes no sense because it’s not a metric fitting but an oddball british deal, you’ll find them on MG’s and similar stuff also)

The autometer lines come with adaptor fittings to connect it to the compression fitting on the back of the gauge.

Most pressure gauges come with either a compression fitting or an NPT fitting on it, pretty much outside of our little world all of them will have NPT fittings.

 

Figure out what the thread is on the gauge and get an adapter from that size to #4 an which is what the long acre is as shown.

You will also need an adapter for the block 5/16 fine to #4 an

Put the adapter to the gauge with teflon tape so it wont leak. The An side of the adapter will not leak when screwed into the hose. If it did not seal it missed a damn good chance.

I run the same set up on my road race car w/80 lbs oil pressure and no leaks. I can not determine what type of thread that you have with your gauge.

Look here www.speedwaymotors.com go to the fitting section and look for adapters.

There's the answer folks!!!!!!!!! Thank YOU!!! Go to your local speed store and tell them what you need, the back of my autometer gauge has the exact same setup, the only difference was mine came with an adapter in the kit.
