does anybody know what LPH rating the stock pump is in my 2000' z?? i had a 255 lph pump inline along with the stock intank pump..and it wasn't enough to feed my car under n20 load..so im either going with a bosch 420lph pump inline or walboro 340 intank and t-rex inline...or does anyone know if they make a 420lph intank pump yet??? thanks,

carter
