Generally, it's located somewhere along the fuel line between the fuel tank and the engine, often near the frame rail. It might be in the engine compartment or underneath the vehicle, sometimes requiring access from underneath.
To find it yourself:
1. Consult your owner's manual: This is the best place to start. The manual will show a diagram of the fuel system.
2. Look for fuel lines: Trace the fuel lines from the tank towards the engine. The filter will be inline. It's usually a cylindrical canister, sometimes with a metal bracket holding it in place.
3. Check online resources: Search for "1998 Chevy Blazer [your engine size] fuel filter location" on sites like YouTube or automotive forums. Many DIY videos show the location and replacement process.
Important Safety Note: Before working near the fuel system, always disconnect the negative battery terminal. Fuel is flammable and working with the fuel system can be dangerous. If you're unsure about any part of the process, take your vehicle to a qualified mechanic.
