Oil Pressure Gauge install questions

Spend the money AND time ONCE by installjng braided steel. It will never break or leak. Also, dont buy "autogage"... Its Autometer's budget line and they suck.
I have installed many styles of gauges over the years in customers cars and not once has a braided line failed in the slightest.

Right now in the shop we have a 66' cbevelle that the customer complains has a noise coming from tbe copper line. We are replacing it.
