Copper. Seems to me that is all I knew of back in the 70's.

Prefer the stainless flex line for oil pressure. Been in the car since the 70's.

The only issue I have had with copper line is it tends to "transmit" engine noise to the gauge.

The concern I have with copper is the fuel gauge that is mounted on the hood.
Every time the hood opens and closes the copper gets work hardened. Thanks for all the replies!

I'm going to use copper on my Sun Oil pressure gauge but going to use Autometer tiny stainless braied line 3an line for my fuel pressure gauge that will be mounted on the cowl.
I'm going to cover both lines witth the chrome wrap that was super popular in the 1970's. The engine vibration and fuel line with copper gives me an uneasy feeling.
