4. Operating Instructions

This tool is specifically designed for the removal of fuel filters and 5/16'' return lines from fuel pump-sending units on applicable Ford vehicles. Follow these steps for proper operation:

1. Prepare the Vehicle: Ensure the vehicle is safely supported and the fuel system pressure has been properly released. Consult your vehicle's service manual for specific instructions on depressurizing the fuel system.
2. Locate the Fuel Filter/Line: Identify the fuel filter or the 5/16'' return line connection you intend to disconnect.
3. Clean the Connection: If the connection is dirty or corroded, clean it thoroughly with a wire brush or appropriate cleaner. Applying a penetrating oil or carburetor cleaner to stubborn connections and allowing it to soak can aid in release.
4. Position the Tool: Place the AST 8012 tool around the fuel line connection. The tool's design allows it to slide into the quick-connect fitting.
5. Engage the Tool: Push the tool firmly into the quick-connect fitting. The tool's jaws will engage the internal retaining clips, releasing the fuel line from the filter or sending unit. You may need to apply gentle pressure while wiggling the line to ensure the clips fully disengage.
6. Separate the Line: Once the tool is fully engaged and the clips are released, gently pull the fuel line away from the filter or sending unit. Avoid excessive force to prevent damage to the line or fitting.
7. Remove the Tool: After the line is disconnected, remove the AST 8012 tool from the fitting.
8. Installation: When installing a new fuel filter or reconnecting the line, ensure the connection is clean and lubricated. Push the line firmly into the fitting until you hear or feel a click, indicating it is securely seated.

5. Maintenance

• After each use, clean the tool with a dry cloth to remove any fuel residue or dirt.
• Store the tool in a dry place to prevent corrosion.
• Inspect the tool periodically for any signs of wear or damage. If the tool is damaged, discontinue use and replace it.
• The rubber band can be replaced if it loses elasticity or breaks.

6. Troubleshooting

• Difficulty Disconnecting: If the fuel line is difficult to disconnect, ensure the fuel system pressure has been fully released. The connection may be seized due to dirt, corrosion, or age. Apply penetrating oil or carburetor cleaner and allow it to soak. Gently push and pull the line while applying the tool to help unstick the internal O-ring.
• Tool Not Engaging: Ensure the tool is correctly aligned with the quick-connect fitting and pushed in completely. Check for any debris preventing the tool from fully seating.
• Line Not Releasing: Verify that the tool is fully engaged and the internal clips are disengaged. Sometimes, a slight rotation or gentle wiggling of the line while the tool is engaged can help.
