Looking for information on upgrading the diameter of the factory fuel lines. At what point is the factory fuel line from the tank up to the fuel filter to small.

 

Its not neccesarily the diameter of the stock lines. More like the banjo type fittings on the filter/tank/rail that are gonna hurt flow characteristics. I did a complete fuel system, as did a couple others on the board.

 

Thank you, My plans were just to remove the factory style filter system and to also change to a straight through fuel rail fitting. But is there a point at which the factory fuel rail becomes to small?

 

Ive heard somewhere around 325hp. But the aftermarket ones look so much nicer!!

 

Someone on here...I think FFGeoff bored his stock one out, it looked pretty good, and most importantly was cheap on the pocket

 

yeah, he did, I think it was just a 1/4" NPT fitting to a hose connector...I may be wrong..

or you can just use a 1/4" to -6AN for the fuel rails and change the banjo fitting to the 12mmx1.25 with a -6 hose end..
