    Fuel Pump Upgrade

    Just was wondering what the factory fuel pump was in lph? as my mods grow its gonna be replaced by a Walbro 255 lph or Racetronix,etc... but for now just wanted to know what the stock one was and where i stand in my mods before i start modding it further.

    Who said it was a v6 lol its an ls1 v8 all the way! and i was wondering what was the "flow rate of the fuel pump" in liters per hour not the injectors or fuel pressure! anyways future mods are gonna be LT's high flow y pipe then an ls6 or better intake manifold to start with.
