Fuel system upgrade
 

well i have to upgrade my fuel system. my biggest question is what kind of fuel pressure regulator should i use? and inline fpr or return style fpr? and how would u recommend me install it on the current stock fuel system? i have a set of 850s in the secondary rails now, but lookin to move those to the primary rails and putting in a set of 1600cc in its place. i need a setup in which will need little modification. u guy have any recommendations?
