Ok this is a pretty lame question, but I am stuck here?

I havent been able to find copper 1/8 tubbing, longer than 6 feet any where?

All of the gauge manufactures only sell it in 6 foot lengths. And the only thing that you can get longer than that is the nylon shit that the gauges come with.

Is it that big of a deal to run nylon? I didnt want to, I figured it would be better to use the copper, I could bend it to follow the contours of under my dash, and in the hood. I can keep the copper bent away from the belts, but the nylon line is to suple and is hard to keep out of harms way.

Every one I asked said homedepot, sears, blah blah blah.

WHERE!!!!!!!!!!!!!! Lol.

I havent found any copper tube in anything smaller than 1/2 or 1/4.

I looked online, summit, egauges, homedepot.com, lowes.com, no where.

I dont want to have to hook up two lines... to make it long enough.

Although I guess I could hookup a copper line for inside the engine compartment, and switch over to nylon line for under the dash. Blah. :flipoff2:

Some hobby shops carry rolls of annealed 1/8 inch copper tubing.

Why not use -03 Aeroquip TFE Braided Teflon tubing? Summit sells it by the ton, and you can make a section as long as you want. Very reliable and easy to tie wrap where you want it.

or just look under metal tubing

not sure if you mean actual or nominal diameter but they have a couple of different kinds in 10 and 50 foot lengths...

Teh nylon stuff isn't all bad. Out in the engine compartment I just run it through a lenght of small diam fuel hose, then run it however looks good and secure it. Keeps it from being exposed, and protects it pretty well.

Last time I bought a coil (15 ft I think) of it I got it at a hardware store. Wasn't sure why they were selling it, but thats wehre I found it.

You know what I will be man enough to tell you that I have no idea either. :flipoff2:

I have an auto meter gauge, and the fitting the threads into the oil filter housing is 1/8, I know because I had to tap it first (it was metric).

So I am making the assumption that I need 1/8 compression fittings and tube.

A good hardware store will have it. Not HD or Lowes. etc.

I know you have said you want copper, but I've also used 1/8" nylon air line that are commonly found on semi trucks. You can get that at most decent auto parts stores. Semi's run constantly w/ 120 lbs of air, so 30-60 psi of oil is no problem.

I know I would not run copper tube in my rig. The vibration could easily fatigue the copper. Yea, I know you could just crimp it if it breaks, but the nylon stuff works fine as long as it is not close to the exhaust.

Ok cool. I guess I will just get a longer section of the nylon stuff... and wrap it in fuel hose or something.

Thanks for the suggestions guys.
