3. Product Overview
The Eagle Tool US AH8028 is a specialized tool designed to safely and efficiently disconnect fuel lines on various Subaru vehicles. It features a precise design to engage the quick-disconnect fittings without causing damage to the fuel lines or connectors.

The image displays two specialized tools designed for disconnecting fuel lines. The blue tool is labeled '8028-1' and the gold tool is labeled '8028-2'. Both are marked 'MADE IN USA'. These tools are used to release the locking mechanism on Subaru fuel line quick-disconnect fittings.
4. Setup
- Identify the specific fuel line quick-disconnect fitting you need to separate.
- Select the appropriate tool part (8028-1 or 8028-2) that matches the size and type of the fuel line fitting. The tools are typically color-coded or marked for easy identification.
- Ensure the tool is clean and free of any obstructions.
5. Operating Instructions
Follow these steps to disconnect a Subaru fuel line using the AH8028 tool:
- After relieving fuel system pressure and selecting the correct tool, position the tool around the fuel line fitting.
- Gently push the tool into the quick-disconnect fitting until it fully engages the internal locking mechanism. You may feel a slight click or resistance as it seats properly.
- While holding the tool firmly in place, pull the fuel line away from the mating component (e.g., fuel rail, fuel filter). The tool will hold the locking tabs open, allowing the line to separate.
- Once the fuel line is disconnected, carefully remove the tool.
- Cap or plug open fuel lines and fittings immediately to prevent contamination and fuel leakage.
6. Maintenance
- After each use, wipe the tool clean with a 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, damage, or deformation. Discontinue use if the tool is damaged.
7. Troubleshooting
- Tool does not fit: Ensure you have selected the correct size tool (8028-1 or 8028-2) for your specific Subaru fuel line fitting. Verify the application against your vehicle's specifications.
- Fuel line will not disconnect: Ensure the tool is fully seated into the quick-disconnect fitting. Apply firm, steady pressure when pushing the tool in and pulling the line out. Verify that fuel system pressure has been properly relieved.
- Tool feels stuck: Do not force the tool. Re-evaluate the alignment and ensure no debris is obstructing the fitting.
