255 walbro Fuel Pump Install

[adidasdudegst]

Ok, so I did some searching, and didn't exactly find what I needed... So when I have the car under accelerating boost around 13-16 psi on the stock turbo, sometimes the car lurches and backfires... I am under assumption, that is because I have the stock fuel pump still... I am correct?

So, if I were to install a new walbro 255 fuel pump, would I have to get a pressure regulator as well, or will the fuel pump just be able to be dropped in?
