Hey guys, yes i searched, and didnt find anything. We are hooking up a fuel pressure regulator to an 88 t2 today. We have 1600s modified to the stock secondary rail, and stock primary...Do we only need to run the regulator threw the secondary rail? Or so we need to do both? Does anyone have a diagram for JUST the secondary rail hookup? And which ports to use? Any help would be greatly appriciated..thanks guys!

 

Well, is your system ran in parallel or a series? If its in series (stock) then the regulator should be installed on the return line, after both rails.
