1. Pipeline quality problem: In this case, only a new pipeline needs to be replaced.
2. The screws at both ends of the oil pipe are loose: the fixing screws at both ends of the vehicle oil pipe need to be checked.
3. tubing aging: tubing can't withstand the pumping pressure of the oil pump, which leads to the tubing bursting automatically. In this case, a new oil pipe needs to be replaced.
4. Incorrect tubing installation: In this case, it is necessary to replace the tubing again, and pay attention to whether the installation is in place.
5. The oil return pipe is blocked: the oil pressure in the oil pipe between the gasoline pump and the carburetor increases correspondingly, which leads to the explosion of the gasoline pipe and needs to be replaced with a new oil pipe.
6. The oil inlet needle valve is not tightly sealed: when the oil in the float chamber increases, gasoline will flow into the cylinder from the carburetor. In this case, it is necessary to replace the inlet needle valve.
7. Aging of tubing sealing materials: The solution is to replace new seals and tubing.
