It may need to be determine by the fuel pump makers, call them to make sure
unfortunately, i have been told conflicting sizes by both the manufacturers and the dealers, depending on what day i called !
just for curiosity's sake, i crawled under my bus to see what kind of setup it had, and it's return line was smaller than the feed. [they are both plastic lines-99 model year] i realize this is just a 3.3 six cylinder, and it's factory designed for that, but that confuses me even more. [if that is even possible !
]
