I'm not sure where to post this but here goes. The little rubber line at the end of the rail by the relief valve has a pin hole in it. It's about 5" long and shaped like a horse shoe. My question is...is that a high pressure fuel injection line or just a return line??? Regular line will bend and not kink, but a piece of FI line kinks. Can I use regular line???? Thanks, John
