I need some sort of hydraulic/braided oil line. I run a Tfitting off my block to my sending unit for my gauge. The copper line blew, I have a nylon on it now, but want something better... any advice?
Unless you have some specific reason for wanting a hydraulic line, the nylon line will last as long as your car. If it's appearance bothers you, cover it up.
The copper was a bad choice as it is subject to cracking from vibration.
