Hey guys i never plumbed my own fuel system, but am about to on my ford focus V8 conversion. I have a custom aluminun fuel cell going into the trunk ara, and need to run a feed and a return line because i am running guel injection on the 5.0 engine. I am a bit confused about sizes, etc... what is -5AN, -6AN, etc?? i cant find any info anywhere as to what sizes these numbers mean, even at the manufacture's websites (russel, aeroquip, etc. I need some of you experts on here to enlighten me as to what you think is the best type of line to run, both for looks and function. It will be a 40 psi system, and i also need to figure out how to connect the lines to the factory style fuel rail, or if i need to get afteramarket fuel rails for the injectors. Thanks a lot for any info
Dan
