i stared and stared at that section of feul line to day and i wanna know, what is UNDER the rubber hosing?
It appears to be a simple piece of rubber hose joining the two ends of the metal fuel lines. I would guess it acts as a flex coupler for the otherwise rigid fuel plumbing. In Sube151's car, you could see the gasoline stains on the stuff underneath the leak. I've been keeping an eye on mine.
