What do you guys recommend for a mechanical oil pressure gauge I've been reading up on the dangers of running a mechanical but I'm not going to run an electric so whats really the best line to use. Right now I'm using just the one that came with the gauge it's away from anything that can heat it up too much or cut it. I am concerned of that chance the line just loses a seal though and starts spraying hot oil inside the cockpit of the car or engine bay for that matter.
