Removal (Durango)
1) Fuel tank may be drained by removing vent hose from rear
of fuel tank, or by pumping fuel from fuel tank using the fuel pump if
fuel pump is operating. If removing vent hose from fuel tank to drain
the fuel, go to step 4). If using fuel pump to drain the fuel tank, go
to next step.
2) Disconnect fuel line from fuel rail. See FUEL LINE AT FUEL
RAIL under FUEL SYSTEM. Connect Fuel Hose (6541, 6539, 6631 or 6923)
for proper engine application at fuel line fitting on fuel rail. Place
remaining end of fuel hose in an approved gasoline container.
3) Connect scan tool to Data Link Connector (DLC). DLC is a
16-pin connector attached to bottom of driver's side of the instrument
panel, just to the right of the brake pedal. Using scan tool
manufacturer's instructions, activate the fuel pump and pump fuel from
fuel tank. Once fuel tank is empty, remove scan tool. Reinstall fuel
line on fuel rail using proper procedure. Go to step 5).
