dude just get a walbro 255LPH. That shit is cheap compared to others and it will work just fine. To top it off, it'll be brand new for about $100.

On another note:
This is my take on fuel enrichment, mostly on Honda systems of pre-7th gen civics and i-VTEC: The best way to increase fuel supply to your cylinder is to get bigger injectors. Higher pressure does not "necessarily" mean higher INJECTOR fuel flow. It just means that more volume is trying to go through the fuel rail, but not necesarily being burnt. The injectors are just like orifices lined up on the rail. Most fuel pressure gauges are mounted on the inlet side of the rail anyway which in theory should increase flow to the fuel rail, then the injectors. The injectors will still pulse on what the ECU is telling it to do.
