I'm replacing mine with copper.
However, I have read of some saying that copper may crack from vibration.
Has anyone heard of or had an issue with the copper tubing?
Copper tubing does become harder over time . If not properly looped for stress relief the vibration will crack it premature . You are correct that copper can fail , this is why the auto industries does not use it . I even had to replace the copper tubing on my air compressor a couple times . Not good in a vibration environment .

Re: Making A New Oil Pressure Line.

My 66 has a steel line which I assume is original. There is no loop in it either.

Is steel w/o a loop correct? I need to look in the AIM to see if there is good illustration on the instalation.

Yeah, steel I read was original.

Yes, steel tubing is still available but it's not as easy to find as copper in this size. One source I've found is Lincoln Industrial. Their part number 62175 is a 25 foot roll of 1/8" OD steel tubing.

I disagree on the generalization of the copper line work hardening. It depends on the type of copper. The copper oil pressure lines I sell are made from 1/8" refrigeration copper that is designed for installation in areas that are subject to heat, cold, vibration, and high pressure. Most of the original lines were mild steel tubing and some of them had a piece of vacuum type hose over the line, I presume to help dampen vibration. Also, some of them were one piece and some of them were two piece with a coupler at the firewall.

Everyone needs to do what they feel comfortable with. I have used the copper oil lines on all of my builds since 2004 with no issues. That would be 6 trucks and 2 Hot Rods......

Re: Making A New Oil Pressure Line.

Great thread.
Kind of on the same subject, when I ran my new oil line I put a T fitting in at the block so I could run both a gauge and an idiot light sender. Figure with something as important as oil pressure, I want a belt AND suspenders.
