Can i just add another higher flow fuel pump on the fuel line without taking off the lower flow rate pump in the tank ~
Thanks for any info =)

Upgrading to bigger turbo and running higher boost ~good question, i want to know too, whats ur intention?
also want to know when do we need to upgrade fuel pump? increased cc from bigger piston can benefit from stronger fuel pump or not when tuning a/f?
Yeah....i have switch to a bigger turbo and running higher boost,now when ever the full boost kick in knocking will occur and the external fuel regulator has been tighten to the max and when the full boost kick in the fuel press drop ~well....its actually depends on the fuel need...normally stock fuel pump still good to serve for fuel needs from 15%-20% power increase....only need to install adjustable fuel regulator.....
but if power increase more than that (turbo most likely) the pump cannot supply enough fuel anymore..thus the need to upgrade fuel pump...other than that no point to change into bigger fuel pump.....
Yeah...in gear 3 6000Rpm the engine turn into Diesel engine,knocks badly,even using Shell V-Power Racing (RON98) it just reduce itDuring full boost if fuel pressure drop is very dangerous you engine may blown anytime. Get a brand new fuel pump and install fuel regulator then re-tune your engine. You need ensure yr fuel press can miantain then re-tune if not you just wasting yr time.
I also think so,but i see on some mat salleh forums,they just put a higher LPH inline pump externally without removing the stock intank pump,so i wonder if this will work =Swilson...i think it is better to remove the old fuel pump along even if u install external fuel pump...afraid if not there's some fuel supply restriction that would affect your new pump efficiency....
Yes,stock fuel rail lack of a return line.....mine is a aftermarket unit from Works ~the stock fuel rail has no return line so max pressure is pumped to the rail right? so i am confused as to how adjustable fuel regulator would help if i need more fuel pressure
and how would i know i need one?
