For 2005+ models, it's non-replaceable and built into the fuel sender assembly
For Chevy Silverado models from 2005 onwards, the fuel filter is non-replaceable and built into the fuel sender assembly. This means that the fuel filter is part of the fuel pump assembly, and therefore, it cannot be serviced separately. Instead, the entire module must be changed. This is because Chevy decided to integrate the fuel filter with the fuel pump.
This design choice means that replacement is more challenging and usually handled by professional mechanics or dealerships. It is a quality, long-life filter that only filters fuel going to the engine. This differs from previous models, where all fuel and recirculated fuel was filtered.
For older Silverado models, specifically those from 1999 to 2004, the fuel filter is located along the frame rail on the driver's side, near the middle of the truck. The location can vary, so you might need to look along the entire rail.

The fuel filter on a Chevy Silverado can be a spin-on filter, which means that it can be replaced without removing the entire fuel line. To change the fuel filter, you will need to lower the vehicle, tighten the fuel filter cap, replace the fuel, and reconnect the negative battery cable. You will then need to turn the ignition on for 2 seconds, turn it off for 10 seconds, and then turn it back on to restore pressure to the fuel system.
It's important to note that the location of the fuel filter on a Chevy Silverado may vary depending on the year and model of the truck. For example, on some trucks, the fuel filter may have been relocated to the engine compartment, while on others, it may be inside the fuel tank or fuel module. Always refer to the specific instructions for your make and model of Chevy Silverado when locating and replacing the fuel filter.
