It is vital to know that the injectors on petrol and diesel engines are distinct, in fact, the difference in combustion between these two types of engines makes the injection distinct. The essential difference lies in the pressure undergone by the injectors, on a petrol engine it will vary between 3.5 bars for indirect injection and 120 bars for indirect injection.
Leaking injector on a petrol Land Rover Range Rover Evoque: The different leaks
It should be noted that injector leaks on a Land Rover Range Rover Evoque equipped with a petrol engine are pretty rare. This is caused by the much lower pressure in the petrol intake systems. However, there are two types of leaks:
