The image presents a compatibility list indicating various Honda Odyssey models from 2014 to 2017. Each entry specifies the year, make (Honda), model (Odyssey), trim (e.g., EX, EX-L, LX, SE, Touring, Touring Elite), and engine details (e.g., 3.5L 3471CC V6 GAS SOHC Naturally Aspirated). This list confirms that the fuel vent tube is designated as "REFNUM: 10" within the vehicle's fuel system diagrams for these specific configurations.

5. Installation

Installation of the fuel vent tube requires specialized tools and knowledge of automotive fuel systems. It is highly recommended that this procedure be performed by a certified automotive technician. Improper installation can lead to fuel leaks, vapor emissions, and potential safety hazards.

5.1. General Installation Steps (Professional Installation Recommended)

1. Preparation: Park the vehicle on a level surface, engage the parking brake, and ensure the engine is off and cool. Disconnect the negative terminal of the battery.
2. Access: Depending on the vehicle model, access to the fuel vent tube may require lifting the vehicle, removing underbody panels, or accessing components from the engine bay or under the rear seats. Consult the vehicle's service manual for specific access procedures.
3. Depressurize Fuel System: Follow the vehicle manufacturer's instructions to safely depressurize the fuel system.
4. Disconnect Old Tube: Carefully disconnect the existing fuel vent tube from its connection points on the fuel tank, charcoal canister, and any other associated components. Be prepared for residual fuel or vapor.
5. Remove Old Tube: Detach any clips or fasteners securing the old tube and remove it from the vehicle.
6. Install New Tube: Position the new Honda Genuine 17726-TK8-A11 Fuel Vent Tube (Part #10 in diagram) into place. Ensure all connections are secure and properly seated. Use new O-rings or gaskets if specified by the vehicle's service manual.
7. Secure Tube: Reattach all clips and fasteners to secure the new tube, ensuring it does not rub against other components or hot surfaces.
8. Reassembly: Reinstall any removed panels or components.
9. Final Checks: Reconnect the battery. Start the engine and carefully inspect for any fuel leaks or unusual odors. Perform a diagnostic scan to clear any related fault codes and verify proper ORVR system operation.

This diagram illustrates the fuel tank assembly and related components, including the On-Board Refueling Vapor Recovery (ORVR) system. The Honda Genuine 17726-TK8-A11 Fuel Vent Tube is clearly identified as item #10, showing its position relative to the fuel tank, fuel pump assembly (items 16, 18, 19, 20), and other vapor lines (items 11, 12, 13). This visual aid is crucial for understanding the tube's placement and connection points within the overall system.

6. Operation

The Honda Genuine 17726-TK8-A11 Fuel Vent Tube operates passively as part of the vehicle's On-Board Refueling Vapor Recovery (ORVR) system. Its function is to provide a pathway for fuel vapors from the fuel tank to the charcoal canister during refueling and normal vehicle operation. It does not require user interaction for its operation. Proper installation ensures its continuous and effective function in managing fuel emissions.

7. Maintenance

The fuel vent tube itself is not a serviceable item and does not require routine maintenance. However, periodic inspection of the entire fuel vapor recovery system is recommended as part of your vehicle's scheduled maintenance. During these inspections, check for:

• Visible cracks, kinks, or damage to the tube.
• Loose or corroded connections.
• Signs of fuel leaks or vapor odors around the fuel tank or canister area.
• Proper routing and secure fastening of the tube.

Any signs of damage or wear should prompt replacement of the affected component with genuine Honda parts to maintain system integrity and compliance.

8. Troubleshooting

A faulty or improperly installed fuel vent tube can lead to various issues related to the vehicle's evaporative emission control system (EVAP). If you experience any of the following symptoms, it may indicate a problem with the fuel vent tube or other EVAP components:

• Check Engine Light (CEL) Illumination: Often accompanied by EVAP-related diagnostic trouble codes (DTCs).
• Strong Fuel Odor: Especially noticeable around the vehicle's rear or after refueling.
• Difficulty Refueling: Fuel pump nozzle repeatedly clicks off during refueling, indicating a blockage or issue with tank venting.
• Reduced Fuel Economy: While less common, severe EVAP leaks can sometimes impact fuel efficiency.

If these symptoms occur, it is recommended to have the vehicle inspected by a qualified technician. Diagnostic tools are required to accurately pinpoint the cause of EVAP system malfunctions.
