What is a Fuel Tank Dent and How Does it Happen?

A fuel tank dent is a deformation of the tank wall caused by external force. Common causes include:

Rock Chips: Especially on unpaved roads or at high speeds, flying rocks can hit the tank and cause a dent.
Parking Lot Bumps: Even minor bumps while parking can be enough to damage the fuel tank.
Accidents: In an accident, the strong impact can significantly damage the tank.
Corrosion: Rust on the outside of the tank can weaken its stability and lead to dents.

Why is a Dented Fuel Tank Dangerous?

A fuel tank dent may seem harmless at first glance, but it poses several risks:

Reduced Fuel Capacity: The dent takes up space in the tank, reducing fuel capacity and the vehicle’s range.
Crack Formation: The deformation can stress the material, potentially leading to cracks. This results in fuel leaks and a significant safety hazard.
Corrosion Risk: Moisture can accumulate in the dent, accelerating tank corrosion.
