If the place where the car is parked smells of fuel or traces of fuel leakage are visible, then some kind of hose or element of the power system is leaking. To determine the location of the leak, you need to park the car overnight in a dry, clean place.
1. Fuel stains under the car?
2. If not, turn on the engine and let it run for a few minutes.
3. After stopping the engine, look for fuel stains under the machine.
4. If there is nothing, then inspect all fuel lines and hoses, as well as all elements of the power system. At the same time, look for damp places with a characteristic smell of fuel.
