47-55

You really shouldn’t use the stock fuel pump due to the hi fuel pressures you will need for the stock injectors. Ditch it and get a walbro.

SEARCH!!!!

He's not saying to ditch the fuel pump because of your idle fuel pressure. The stock pump can't keep up with the need for the high fuel pressures once in boost when using a 12:1 fmu and stock injectors, you will run lean without the walbro
