[QUOTE="Mdub707, post: 81736, member: 107"] It just doesn't make any sense to me. The ports in the heads run past the last injectors anyways. So if your pump can hold 60psi in the heads, how would one injector starve over the other? If pressure was dropping hard when you accelerate I would agree, but as long as a pump can keep a specific volume (your heads) at 55psi, no matter how much is draining out (ie, your injectors using fuel) then what difference does it make where or how it's regulated, as long as it is? The AD2 can be regulated at the pump, so if you've already got that, I see no need for a regulator up at the heads like the ITP setup. I'm not saying it's a bad thing to have, and not faulting it at all, but I know if I already had a RR pump, I wouldn't be worrying about adding another at the back of the heads. All boils down to having a fuel pressure gauge and knowing if your truck needs more fuel or not. As long as pressure is there, you should be good. No? [/QUOTE]
