Just to be safe I'm looking to make 500rwhp and then put a 250 direct port shot on top of that.

My fuel system is a return line style system that goes (starting at the tank):

- Walbro 255Liter pump
- stock supply line (I removed/plugged the "T" for the stock return setup)
- 97/98 vette fuel rail (adjustable pressure regulator on rail)
- stock sized (actually EVAP line) return line from rail



so it boils down "How much HP can a single Walbro 255 and a stock supply line support?"

If my system will not support what I'm looking to do, "Would sticking a second Walbro 255 in the tank help any or am I just limited by the stock supply line? How large should I go up to?"

thanks
