Hey fellas, I'm refreshing/upgrading my fuel pressure regulator lines to teflon lines. I'm trying to figure out the barb fitting size needed for the rubber hose that connects to the hardline going back to the fuel tank (the one by the firewall). Which barb fitting size do I need for that hose? 5/16? what would be that in mm?
I need to redo the line that goes from the bottom of the AFPR to the return line which is why I need the barb fitting.
Thanks
Thanks
