2016 Fiesta 1.24 - Petrol Smell - jc2

Recently,I have noticed a strong smell of petrol at the lower back of my car when parked.Thinks!It could be the purge line come off the Evap. canister or a leak in the return fuel line but as there is no evidence of wet fuel,I think the second cause is unlikely.Both these would need the tank dropped to check.Further thinking,All my driving recently has been a one- mile each way journey to a local supermarket.As the canister is only purged when engine is in "closed loop" mode ie.not idle or "WOT",could this be the cause?Any other ideas please?

A fault/leak in the evap system circuit would probably cause poor running and possibly illuminate the engine fault light. Many late Fords use a returnless fuel system, so there is only one pipe from the tank to the engine. Short journeys could mean evap system not up to operating parameters.

The only fault in the evap system that would illuminate the fault light is control valve failure-all 1.24 Fiesta are two pipe fuel systems.I agree with you on short journeys-one day,we'll get a chance to do long ones again.Purging on "closed loop" means it does not matter if it's air or fuel vapour that's being purged,the control system will compensate.
