Here's the data for '97.
The fuel pump for the:
3.0L (2V) is capable of supplying 80 liters (21.1 gallons) of fuel per hour at 269 kPa (39 psi) at 13.2. volt.
3.0L (4V) engines are capable of supplying 120 liters (31.7 gallons) of fuel per hour at 269 kPa (39 psi) at 13.2. volt.
3.0L (2V) FF vehicle is capable of supplying 125 liters (33 gallons) of fuel per hour at 269 kPa (39 psi) at 13.2. volt.
