Spanish mechanic Juan José Ebenezer warned about a fuel leak problem that can go unnoticed for a long time and, under certain circumstances, increase the risk of fire. The specialist analyzed the case of a car that occasionally lost gasoline, especially after filling the tank.
The leak was difficult to detect because it disappeared after the car had traveled a few kilometers. When the owner arrived at the workshop, the fuel had already dropped in level and the dripping was no longer visible. To identify the source of the problem, the mechanic had to partially disassemble the wheel area and simulate filling the tank, discovering piping and rubber components already degraded over time. Two simultaneous leaks were identified: one in the main filler piping and another in a smaller tube.
During hot months, the problem becomes even harder to detect because gasoline evaporates quickly and may not form a visible stain on the ground. The fire risk increases when fuel reaches very hot areas of the vehicle, such as brake discs, or electrical components capable of generating an ignition source.
Juan José recommends that drivers be on the lookout for signs such as abnormal fuel smell, inexplicably higher consumption, or traces of gasoline after filling the tank. The necessary repair was relatively simple, requiring only the replacement of the deteriorated hoses and tubes. The mechanic also recalled that many older cars maintain mechanically simple faults to repair, as long as maintenance is carried out in a timely manner.
