Type B Removal
CAUTION:
- Be careful not to damage the pipe when unlocking the retainer.
NOTE:
- When a prompt connector is detached, following SST can be used.
- 49 N013 103A
- 49 E042 001
When using SST 49 N013 103A
1. Follow "BEFORE SERVICE PRECAUTION" and remove dirt from the connecting surfaces before performing any work operations. Before Service Precaution
2. Verify that the quick release connector joint area is free of foreign material. Clean if necessary.
3. Install the SST as shown in the figure and push into the quick release connector to disconnect the fuel pipe.
4. Cover the disconnected quick release connector and fuel pipe to prevent them from being scratched or contaminated with foreign material.
When using SST 49 E042 001
NOTE:
- If the quick release connector is removed, replace the retainer with a new one.
1. Follow "BEFORE SERVICE PRECAUTION" and remove dirt from the connecting surfaces before performing any work operations. Before Service Precaution
2. Set the SST parallel to the quick release connector.
NOTE:
- The quick release connector can be removed by pushing the center of the retainer tabs.
- The retainer is attached to the pipe even after the connector is disconnected.
3. Hold the center of the retainer tabs with the SST ends and press the retainer.
4. Pull the connector side and disconnect the quick release connector.
5. Raise a retainer tab using the SST and remove the retainer.
6. Cover the disconnected quick release connector and fuel pipe with vinyl sheeting or a similar material to prevent it from scratches or dirt.
Type C Removal
1. Move the retainer upward using a small flathead screwdriver or a similar tool.
2. Pull out the evaporative hose straight from the joint port and disconnect it.
3. Cover the disconnected quick release connector and joint port with vinyl sheeting or a similar material to prevent it from becoming scratched or dirty.
Type D Removal
