Where is fuel filter on 1995 s10?

The fuel filter on a 1995 Chevrolet S10 is located on the frame rail, near the fuel tank. It's usually a cylindrical canister. To be precise, you'll need to look along the driver's side frame rail, somewhere between the rear axle and the fuel tank. However, the exact location can vary slightly depending on the engine and other options on your specific truck. A repair manual or a detailed online diagram for your exact year, make, and model would be helpful for pinpointing it.
