The filter is part of the fuel pump assembly
The fuel filter on a 2007 Chevy 3500 Silverado depends on the engine type: gas or diesel.

Diesel models with a Duramax engine will have the fuel filter on the passenger side, below the air intake tube.
The fuel filter on a gas model Chevy Silverado can be replaced by removing the center air intake tube between the air filter housing and the turbocharger. The passenger side inner fender can then be removed. The water-fuel separator drain valve can be found at the bottom of the fuel filter, and should be opened, along with the bleed screw at the top of the fuel filter housing. The remaining fuel should be drained into a container and disposed of appropriately.
On a diesel model, the filter is part of the fuel pump assembly. To replace the fuel filter, the fuel tank must be dropped, and the fuel pump assembly removed. The assembly can then be replaced, along with the filter, and sealed properly.
It is important to note that replacing the entire fuel filter housing is often simpler and faster than just replacing the fuel filter, as the housing includes the head, filter, and water-in-fuel sensor. This process can be done at home, with the right tools, and following the correct procedures.
