the thing about the walbro is it is higher quality (generally) and can provide the necesary volume & pressure (well within specs, similar to injector duty cycle...) for the injectors & FPR......using a smaller/stock lph pump will be doing alot more work I am assuming. My guess would be that the fuel line will have less pulsations in fuel pressure. IMHO I would replace pump just because, bigger & new pump is always good....i would just go for the high performance over OEM
