Type B
An SST is used with this type.

Consists of a retainer and O-ring. The quick release connector is integrated with the fuel hose and therefore cannot be disassembled.
To connect the quick release connector properly, push it into the fuel pipe until a click sound is heard.
New quick release connectors are fitted with a checker tab that prevent improper installation. This checker tab cannot normally be removed. When the quick release connector is properly connected to the fuel pipe, the lock is released and the checker tab comes off. Due to this, it can be verified that the quick release connector is completely connected.
