Another forum post of rubbing front plug wire on the fuel tank. Some said it was 25% worn though some said it was just a slight mark. Seams there is a clip attached to the tank some said wire was not attached to the clip some said the clip was not there. Of course everyone reported theirs was rubbing.
I checked mine with 5600 miles, there is a very slight rub mark on the wire. Installed section of rubber hose on that section should solve the problem.
Just thought you might want to check your plug wire. Long term it could be a problem but looks to be an easy fix and not an issue short term.
