Fuel Delivery - Diesel - Draining Fuel Tank
WARNING: This page is about a different car, the 2008 Dodge Magnum, 2008 Dodge Charger, and 2008 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
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.
