Factory Oil Pressure Gauge Leaking

Pretty sure that the general didn't ever use copper for a pressure line. It work hardens and cracks. There's going to be engine vibration, which would be enough.

I respectfully disagree. The General didn't use copper tubing because of the cost differential. There are millions of feet of copper tubing used in refrigeration units that are subjected to high heat, high pressure, and a lot of vibration. Member "Tx Firefighter" said that big trucks also use it for air shifter lines.

Here are the specs for the copper tubing I use for the oil pressure lines I sell.....

As long as the oil line is installed with vibration dampening coils as shown in this thread. ( https://www.67-72chevytrucks.com/vbo...d.php?t=613238 ) There would be no problem with copper tubing.

I stand corrected.
