TBI Swap Fuel Pump Quandary

[JCampbell]

I'm getting ready to order my fuel pump for my TBI swap. I'm planning on running the Carter P5001, but after looking at the specs of the P5001 vs. the P5000, I have a slight hesitation.

The P5001 runs 9-22 psi @ 50 gph whereas the P5000 runs 22-75 psi @ 50 gph.

The numbers fluctuate depending on who you ask, but seeing as how TBI only needs anywhere from 9-13 psi, is there any advantage to running the larger pump? It's never going to be a high-horse, monster engine. Just a real streetable 454 with a small RV/towing cam and intake.
