i would buy either a 190 or 255, but to answer your question no it wont affect anything it will just give you the xtra fuel when needed.

What he said. Your regulator will determine howmuch the fuel flows. Go with a walbro 255 then you will have the fuel pressure when you build your engine.

no, the engine will only use what it needs, the 255lph rating is what it CAN supply, not what it WILL supply
