When the fuel filler connection pipe (usually refers to the fuel tank refueling hose) is damaged
Temporary first aid measures
For leaking fuel pipe joints:
Wrap cotton yarn around the joint in the tightening direction, and then tighten the joint.
Apply soap to increase sealing and lubricity.
For broken fuel pipes:
Apply soap to the broken part first to slow down the oil leakage.
Tightly wrap the broken part with soapy cloth, tape or plastic.
Tighten the wrapped part with wire and apply a layer of soap to increase sealing.
Note: These first aid methods are only temporary countermeasures and cannot replace professional repairs. The vehicle should be sent to a professional repair station for inspection and replacement of new fuel pipes as soon as possible.
Long-term solution
Replace damaged fuel pipes:
Open the vehicle inspection port.
Remove the fuel inlet and return pipes at the fuel tank.
Connect the new fuel pipe to the corresponding joints and tighten the connection with a wrench.
Tie the fuel pipe and avoid getting close to the high-voltage line.
Connect the fuel inlet pipe to the engine or fuel filter to ensure smooth fuel flow.
Check and replace sealing materials:
Check whether the sealing materials at the oil pipe joints and switches are aged or damaged.
If necessary, replace new gaskets or sealing rubber rings.
Preventive measures:
Regularly check the condition of the oil pipe, including signs of aging, cracks, wear, etc.
Avoid collisions and scratches on the oil pipe during driving.
Add the appropriate amount of lubricant as required to avoid adding the wrong fuel.
Safety precautions
When replacing or repairing the oil pipe, always ensure that the vehicle is in a safe state to avoid dangerous situations such as fire or explosion.
Follow the advice and guidance of professional maintenance personnel to ensure the safety and effectiveness of the maintenance process.
