1993 Legacy Turbo


The service manual specifies the WRX fuel pump should flow at least 130 liters per hour at 43.5psi with a 12 volt power supply.

The RS (MY02 anyway) pump flows at least 65 lph at 43.5psi and 12v.

Since I have this info handy, I'll add it too:

90-94 Legacy non-turbo: at least 80 lph at 36.3psi and 12v
91-94 Legacy Turbo: at least 150 lph at 43.4psi and 12v
