ok my issue is i have an aeromotive fuel system ,bung off the rear of tank ,then through a 100 micron filter then fuel pump,then bypass regulator ,all underneath the truck .im installing rails and new inj this weekend ,with the regulator off the rails.2 things.1 is that i have too let the fuel pump come all the way on b4 i can start the truck ,like build up the pressure all over again .factory i could just fling the key and sterter up .now i have to wauit until pressure builds up then start ,pia.any solutions for this deal?and 2 i have a buddy that builds dragsters and he puts his reg ulator after the rails.another words hes saying go in at whatever pressure the pump is putting out then regulate it at the other end of the rails .in 100 psi then regulate it at thhe other end of the rails ,dont seem right ,i was gonna regulate b4 the rails then crossover at 58-60 psi.i need youre opinions or pics of youre rail setups i only want to do 1nce .now granted i dont want to put my buddy down cause he knows his **** on old smallblocks with 9 psi,but i want to be sure of my options.i def want to put my regulator up top now just for ease of adjusting f/p.thanks guys.
