[QUOTE="Mdub707, post: 638188, member: 107"] As long as your pump can keep the volume flowing. Theoretically in a sealed system, pressure should be constant throughout, though I doubt it actually is in this case. I bet pressure is substantially less after the injectors than it is at the fuel bowl. Honestly I think the fuel bowl is one of the worst options for placing a fuel pressure sender. Guys running a big pump with a RR probably wont have these issues. There are guys out there running say 155's or 175's with a stock pump and no RR. It's more aimed at those guys. Some guys read pressure at the fuel bowl and think they're ok with fuel pressure. I'm going to to attempt to prove that thought one way or the other. I was originally reading fuel pressure down on my vegistroke manifold for a while (behind the heads) and on diesel, new OEM pump, stock injectors, blue spring upgrade, and old style fuel filters, on a MILD street tune I could easily drop fuel pressure back there down to 25psi or so.
