Where is the fuel filter on a 1986 Chevy c10 truck?

On a 1986 Chevy C10, the fuel filter location depends on the engine. There's no single universal location. It's usually mounted on the frame rail, somewhere along the length of the fuel line between the tank and the engine. However, it could be closer to the engine or closer to the fuel tank, depending on the specific model and options.

To find it, you'll need to:

1. Consult your owner's manual: This is the best place to start. The manual should have a diagram showing the location.

2. Look along the frame rails: Carefully examine both frame rails from the fuel tank towards the engine. The fuel filter is usually a cylindrical canister, sometimes with a clear bowl section to visually check fuel clarity. It might have fuel lines connected to it with clamps.

3. Trace the fuel lines: Follow the fuel lines from the fuel tank and from the fuel pump to the carburetor or fuel injection system. The filter will be in-line along this path.

4. Use a repair manual: A Haynes or Chilton repair manual for your specific year and engine will have detailed diagrams and instructions.

Because there's no single definitive answer without knowing the specific engine, using these steps is crucial to locating your fuel filter. Be careful when working near fuel lines – avoid sparks and open flames.
