I had a longtime fuel smelling and leaking problem and got also sprayed with petrol during the last summer.
The reason was a buckled petrol hose between the petrol tank and the roll over valve on top of the tank. The underlying cause was a broken bracket of the roll over valve. Subsequently the pressure in the petrol tank is encreased.
Now I‘ve fixed the roll over valve and renewed the petrol hose - all problems are solved since I made this modification.
