Claims

[Scope of utility model registration request]

In the seat insertion part of the body of the fuel filter, the fuel inlet passage and the unused fuel passage are connected at approximately 90 degrees.
The primary side air bleed passage and the air outlet passage are formed with a positional interval of approximately 135°, respectively, and the valve lever can communicate with the fuel inlet passage and the unused fuel passage through a seat. forming an air bleed passage that can communicate with the primary air bleed passage and the air outlet passage, and further form a secondary air bleed passage in the body that is in constant communication with the air bleed passage; A fuel filter tank characterized in that the air bleed passage, the primary side air bleed passage, the secondary side air bleed passage and the air outlet passage are brought into communication only when the valve lever is rotated to the "air bleed" position.
