fuel presure

[03busa]

Hi,how can i up the fuel pressure on the busa? It can be done so i have been told but need some help.

crush the regulator length ways about 0.9-1.0mm and you,ll end up with around 55psi.I bet youve got a dirty pleated filter though,which is what the pump pushes up into,not the little screen on the bottom of the pump.
