Draining Fuel Tank - Diesel

A one-way check valve is located within the fuel fill fitting on the fuel tank. Because of this valve, the tank cannot be drained the conventional way through the fuel fill opening.

To drain the tank, the fuel pump module must be removed.

1. Remove fuel tank (Refer to FUEL SYSTEM/FUEL DELIVERY/FUEL TANK - REMOVAL) .
2. Remove fuel pump module (Refer to FUEL SYSTEM/FUEL DELIVERY/FUEL PUMP MODULE - REMOVAL) .
3. After fuel pump module has been removed, drain fuel into an approved diesel fuel oil draining station.
