As a side note of the above, on stock fuel lines and high hp setup I personally prefer to have both a pickup and an inline pump, a pick up pump such as the walbro 255 and an inline such as the bosch 044 with both pumps hardwired or just the second if you wish. The specific pump combo works very well either way and has no cavitation issues. Change FPR and fuel rail for above 700hp, change fuel lines for above 800hp and you are good to go.

Great info, I was always concerned with over running the OEM FPR meaning that the base fuel pressure is risen as the stock unit cannot handle the extra fuel.
