I was underneath the Bullitt today,making an adjustment to the exhaust tailpipe,and happened to notice how small the fuel line looked. Put the calipers to it,and it specs out at 5/16ths of an inch on the O.D. I would have thought they would be 3/8ths in dia. with todays HP fuelie engines. Do the '03-'04 Cobras,Mach 1 Mustangs use the same size line? How about the 2008 Bullitt?
