To find it, you'll likely need to:
* Consult your owner's manual: This is the best resource. It will have diagrams and specific locations.
* Look under the vehicle: Many are located along the frame rail, near the fuel tank.
* Trace the fuel line: Start at the fuel tank and follow the fuel line forward. The filter will be somewhere along that line. It's often a cylindrical canister, sometimes with a metal bracket holding it in place.
Be aware that accessing it might require getting under the truck, and working with fuel can be dangerous. Take precautions if you decide to locate and change it yourself.
