This bulletin is being issued to inform technicians of additional information regarding replacement of the fuel filler door spring.
If the spring is being replaced for breakage and it occurred during cold temperatures, it may be due to water intrusion. Water may enter through the seams in the housing and freeze. If the spring is pushed in to open the fuel door, the force will cause
the housing to separate.
A new fuel filler door spring will be available in the near future. In the meantime, to prevent reoccurrence, engineering is recommending that prior to installing a replacement spring, to apply a flexible sealer such as 3M™ Clear Auto
Sealer P/N 08551, or equivalent, to the voids (1) on both sides of the spring housing as shown in the picture below.
