Smell of gasoline in the room of an escort 1.8

My niece has bought an escort 1.8 (105) and smells a lot to gasoline in the habitaculus. I have made a look at the first view I don't see anything. If someone comes up with something tell me where to continue that I am lost. Thank you

Take out the rear seat and check the orring where the cables enter the pond, most likely it is cut or bite and there escapes the smell

I already checked that rubber and apparently it seems to have anything. They tell me on the other hand that it can be of a sleeve. I will keep looking at if I get it. Thank you so much.
If someone has the workshop book and it can happen to me, it would be appreciated because instead of a car it looks like a grandfather with so many achaches that come out. Thank you.

Czech the flexible of the escape line you want is broken and the smell gets into the abitaculus there, luck

Thanks for the information. I will take a look if there is luck and it is there.
