Fuel Tank Draining: Notes
WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Gasoline or gasoline vapors are highly flammable. A fire could occur if an ignition source is present. Never drain or store gasoline in an open container, due to the possibility of fire or explosion. Have a dry chemical (Class B) fire extinguisher nearby. Always wear safety goggles when working with fuel in order to protect the eyes from fuel splash. Fuel vapors can collect while servicing fuel system parts in enclosed areas such as a trunk. To reduce the risk of fire and increased exposure to vapors: Use forced air ventilation such as a fan set outside of the trunk. Plug or cap any fuel system openings in order to reduce fuel vapor formation. Clean up any spilled fuel immediately. Avoid sparks and any source of ignition. Use signs to alert others in the work area that fuel system work is in process.
CAUTION:
Do not force a hose or the siphon of a hand operated pump into the fuel tank. Forcing the hose or siphon into the fuel tank can damage the check valve located in the fuel filler pipe.
NOTE:
Drain the fuel from the complete system, including injector nozzle(s), the fuel pump, all fuel pipes, and the fuel tank if a vehicle is to be stored for any appreciable length of time. Draining the fuel will prevent the formations of fuel system deposits.
