Dont get me wrong, I'm all for the extras and I dont even know if my theory is true. Its just a theory. With that said....

The FPR is the last thing the fuel sees before it hits the fuel rails. I wouldn't think the stress would be on the fuel rails anyways, considering most people run ~38psi pressure. The back pressure I was referring to is what you are going to have in the fuel lines between the tank and the FPR. You could always up the pressure at the fpr to compensate for the added pressure of the pump, but then you will run incredibly rich and thats not good. Its obvious that the 19 lb/hr injectors dont flow as much as the 24# and up. If you went with the larger injectors, again you would have to reduce the pressure at the fpr so as not to flood the cylinder with too much gas, which will result in even more backpressure in the fuel lines. Remember, this is all theoretically speaking. I may be way off in my thoughts. I'd say until you add the blower replace it with a stock unit, I cant imagine they are too expensive. But that is just what I'd do. If any of this "theory" is wrong, someone correct me please.
