Tools Required

SA9127E Fuel Flow/Pressure Test Adapter

For any operation requiring removal of the fuel tank, there should be no more than 11.4 liters (3 gallons) of fuel remaining. This minimizes the weight of the assembly and eases handling. The fuel level can be determined by reading the fuel level gage. A reading below 1/4 full indicates that no more than 11.4 liters (3 gallons) are remaining.

Caution: Refer to Gasoline/Gasoline Vapors Caution in the Preface section.

Caution: Never drain or store fuel in an open container due to the possibility of fire or explosion.

Using the fuel pump to drain the tank is the easiest procedure if the pump is operable. The fuel can be pumped out with the vehicle on the ground or on the hoist.

Caution: Refer to Relieving Fuel Pressure Caution in the Preface section.




1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief .
2. Disconnect the fuel feed line at the fuel rail and install a 3/8 in x 1/4 in quick connect from the SA9127E into the fuel feed line.
3. Connect a suitable drain hose to the other end of the adapter and connect the drain hose into a certified fuel handling cart.
4. Connect a scan tool to the vehicle and turn the ignition ON.
5. Energize the fuel pump using the scan tool. Refer to Energizing the Fuel Pump.
6. Pump out the fuel until no more than 1/4 tank remains.

1. Connect a scan tool to the vehicle diagnostic connector and turn the ignition ON.

Caution: Refer to Relieving Fuel Pressure Caution in the Preface section.

2. Relieve the fuel pressure. Refer to Fuel Pressure Relief .

Caution: Refer to Vehicle Lifting Caution in the Preface section.

3. Raise the vehicle on a hoist to a comfortable working height, keeping the scan tool outside of the vehicle and accessible from under the car.

Caution: Refer to Relieving Fuel Pressure Caution in the Preface section.
