Fuel Tank Draining

WARNING: This page is about a different car, the 2005 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: THE FUEL SYSTEM MAY BE UNDER CONSTANT FUEL PRESSURE EVEN WITH THE ENGINE OFF. THIS PRESSURE MUST BE RELEASED BEFORE SERVICING FUEL TANK.

Two different procedures may be used to drain fuel tank: through the fuel fill fitting on tank, or using a diagnostic scan tool.

The quickest draining procedure involves removing the rubber fuel fill hose (3) from fuel tank fitting (7).

As an alternative procedure, the electric fuel pump may be activated allowing tank to be drained at fuel rail connection. Refer to scan tool for fuel pump activation procedures. Before disconnecting fuel line at fuel rail, release fuel pressure. Refer to STANDARD PROCEDURE - FUEL SYSTEM PRESSURE RELEASE for procedures. Attach end of special test hose tool number 6541, 6539, 6631 or 6923 at fuel rail disconnection (tool number will depend on model and/or engine application). Position opposite end of this hose tool to an approved gasoline draining station. Activate fuel pump and drain tank until empty.

If electric fuel pump is not operating, fuel must be drained through fuel fill fitting at tank. Refer to following procedures.

Release fuel system pressure.
Raise vehicle.
Thoroughly clean area around fuel fill fitting (7) and rubber fuel fill hose (3) at rear of fuel tank (8).
Loosen clamp (9) at tank fitting (7) and disconnect rubber fuel fill hose at fuel tank fitting. Using an approved gas holding tank, drain fuel tank through this fitting.
