I want metal tubing not plastic for my oil pressure gauge!

I guess I am the odd man out. I always preferred the nylon line when I ran a manual gauge. I have run the copper line and every time without fail, I had it break. Since the engine moves independently from the body, there is always flex. The nylon eliminates that breakage problem. But, as mentioned already, electric gauges are best. No need to run oil into the passenger's compartment. This is the 21st century, after all.
