Possible Causes Categorized by System, Why is gas leaking from the bottom of my car
Identifying the source of the leak is the first step toward effective repair. Categorizing potential causes by system—fuel, exhaust, or other—allows for a focused diagnostic approach. The table below illustrates the potential components within each system that might be causing the leak.
| System | Component | Potential Leak Cause |
|---|---|---|
| Fuel System | Fuel Tank | Corrosion, cracks, or punctures in the tank, improper sealing of filler cap. |
| Fuel System | Fuel Lines | Wear and tear, punctures, deterioration from age or exposure to chemicals. |
| Fuel System | Fuel Pump | Damaged seals, worn-out components, or leaks around the pump assembly. |
| Fuel System | Fuel Injectors | Damaged or cracked injectors, worn-out seals. |
| Exhaust System | Exhaust Manifold | Cracked or deteriorated manifold, loose or damaged gaskets. |
| Exhaust System | Exhaust Pipes | Corrosion, holes, or damage from road debris or impacts. |
| Exhaust System | Exhaust System Gaskets | Gaskets worn, deteriorated, or not properly installed. |
| Other | Engine Mounts | Cracks or damage to engine mounts, allowing for component movement and leaks. |
| Other | Transmission Pan | Leaks around the pan or a failing seal. |
