Fuel Tank: Testing and Inspection

LEVELING VALVE CHECK





1. Place a drain pan, and disconnect the fuel tank vapor hose A at pipe side.
NOTE:
If fuel leaks from the fuel leveling hose at this stage, the leveling valve may be defective.

2. Open the fuel cap, and fill the fuel tank up.
3. If fuel does not leak from the fuel tank vapor hose A with the fuel tank full, the leveling valve is normal. If it does leak, the leveling valve may be defective. Lower the fuel tank from the vehicle and replace the valve.
4. Reconnect the fuel tank vapor hose A at the pipe side.
