I wouldnt run a wet kit on the stock fuel pump end of story. You can get a Walbro 255hp for like 100 bucks.

Running a wet kit on a stock fuel pump is fine. Max shot I'd say would be a 75 shot. I'm running a 75 on a stock pump. But, since you're PSi is at what? 18? I'd recommended a pump upgrade, just due to the fact that you're at a higher boost level than stock, and by running a wet kit off of your fuel line could hinder your fuel/air ratio mixtures for the higher boost levels.

I would love to see what happens to your fuel pressure under boost.
