Fuel Tank Draining Procedure

Tools Required

J 43290 Fuel Tank Siphoning Hose
J 42960-2 Fuel Flapper Door Holder

CAUTION: Never drain or store fuel in an open container. Always use an approved fuel storage container in order to reduce the chance of fire or explosion.

CAUTION: Place a dry chemical (Class B) fire extinguisher nearby before performing any on-vehicle service procedures. Failure to follow these precautions may result in personal injury.

Remove the fuel filler cap.
Install the J 42960-2 , or equivalent, into the fuel fill pipe in order to hold the door open.
Insert the J 43290 (2) through the J 42960-2 (1) and into the filler pipe.

Continue to insert the J 43290 (2) into the filler pipe until the hose exits the valve (1) and reaches the bottom of the tank.
Use an air operated pump device in order to drain as much fuel through the J 43290 (1) as possible.
