Anyone use it or could tell me for my application its going to be OK:

My mods are listed below, my fuel system currently is Stock pump and Vortech FMU 12:1 (getting recalibration kit in the mail in the next few days, all the discs)

I ordered the MSD inline fuel pump which specs are:
Multiport EFI systems require a stable fuel supply to maintain best performance throughout the engine’s rpm range. This high pressure and high flow Fuel Pump features a roller vane pump mechanism which is extremely resistant to clogging and jamming. The pump mounts in-line (out of the fuel tank) with two supplied cushioned clamps for a quick and sturdy installation. The nipple inlet is 3/8” with a 5/16” outlet. The wire terminals feature brass studs for secure connections. Made in the USA, the pump is ideal for use as a “booster” for nitrous oxide applications, or as a stand alone pump for multiport EFI systems on engines up to approximately 500 HP. Capable of 43 gph at 40 psi/162l/h.

Is that going to work for me? It says 162lph and at 40-43psi? I'm running 7psi right now... please let me know any suggestions/comments you have.
