I ordered the 255 LPH fuel pump because it was only 10 dollars more on this site I saw. Would I have any problems running this pump in my fuel tank without having any forced induction? I'm guessing it should still run the same as a stock fuel pump just with the ability to pump out more liters.

 

I have it and no problems, the car doesn't run rich or anything since the stock FPR can handle it.

 

yeah, you should be fine. your car will only run rich if the fuel pressure somehow increases or if you increase your injector size without any ecu changes.
