Download Some of the vehicles affected by this campaign may contain a fuel tank assembly valve that may not close properly. This TSB provides the procedure to remedy this condition by installing an additional fuel tank assembly valve. For Sonata and XG350 vehicles (Please see pages 8-10 for Elantra and Tiburon vehicles): 1. Raise the vehicle. 2. Remove the three muffler hangers and support the rear muffler after it has been lowered 6 inches. NOTE: Do not allow the muffler to hang unsupported. Do not lower the muffler more than 6 inches. 3. Remove the rear suspension crossmember mounting bolts and lower the suspension crossmember. 4. Support the fuel tank using a jack stand. 5. Remove the left rear fuel tank band nut and lower the band from the mounting stud. 6. Disconnect the vapor hose from the ‘Y’ shaped tube. 7. Cut about 4 inches (100mm) from the end of the vapor hose as shown. Discard the 4 inch piece that you have removed. 8. Install the new valve bracket mounting hole over the fuel tank band stud and connect the cut end of the vapor hose to the lower nipple of the new valve. NOTE:
