This bulletin was released by Subaru, relating to the 2010-2012 Outback. If you have a customer concern of difficulty filling the fuel tank, be aware it may be the filler neck hose.
Subaru notes that they have had fuel tanks replaced for this concern because the hose was not removed with the tank and inspected for obstruction. Because of lighting and location, a quick look at the outside of the hose may not show any problem. The hose needs to be removed and light directed into the hose, on both ends.
