Yes but such a powerful pump can over power the stock injectors, and fuel regulator.

Indeed, a walbro can raise rail pressure above 40psi if the regulator can't bypass enough, and injectors flow more CC at higher pressures at the same duty cycle.

I had mine rewired to constant 12v before, it made flooding a bitch when I broke my engine in, as soon as I rewired it again, it stopped flooding and ran a lot better., so yes it can def give u too much fuel
