Install the J 42960-2 into the fuel fill pipe in order to hold the door open.

NOTE: Lubricate the fuel drain hose with J 36850 or equivalent to aid in hose insertion. Do not use an unapproved lubricant.

Insert the J 45004 into the fuel tank until the hose reaches the bottom of the fuel tank.
Use a hand or air operated pump device in order to drain as much fuel through the fuel fill pipe as possible.
