What You'll Learn

The 2005 GMC Envoy fuel filter is located inside the tank
Some sources suggest that the fuel filter is a "sock-type filter" located right below the pump, inside the tank. This is supported by the fact that, when the fuel pump dies, it can send plastic and metal pieces into the fuel rail and damage the injectors. This is because GM removed the fuel filter between the fuel pump and the engine in 2005 models.
The fuel filter is also referred to as a "pad" at the bottom of the fuel pump. This is the only filter in the 2005 GMC Envoy, and it is non-serviceable due to its location inside the tank.
The procedure for replacing the fuel filter in the 2005 GMC Envoy is the same as for other models, although the location of the filter is different. It is recommended to refer to the owner's manual and seek professional assistance when replacing the fuel filter.
