Does is smell for gasoline under your hood ?

Remove the air filter (black round thing right to the engine). You will see the air intake and a fuel distributor unit. Behind the fuel distributor is a black plastic box attached to the distributor. That thing may leak. It might be sufficient to unscrew it (2x torx) and replace the two o-Rings. Warning: cover the box with cloth until both screws are loose ! Gasoline may spray out with high pressure.
