However, the detection devices in the prior art are not convenient for fixing the fuel rail, resulting in a long time spent during detection. At the same time, foreign objects blocking the fuel rail cannot be removed by pressure. Therefore, there is an urgent need for a conduction detection device for a fuel rail channel to overcome the above defects. Summary of the Utility Model
