Where is the fuel filter on 2011 GMC Sierra 1500?

On the 2011 GMC Sierra 1500, the fuel filter is located inside the fuel tank as part of the fuel pump module. This design means that the fuel filter is not easily accessible for replacement, and if it needs to be changed, the entire fuel pump assembly typically needs to be removed from the tank. Regular fuel system maintenance, including using quality fuel, can help prolong the life of the filter.
