here is a link to a late ducato fuel tank and it shows the filler neck
from what you have described i would have thought that you may have a small leak somewhere up the top of the filler neck and looks like if you drain the tank you should be able to remove the filler neck to have a look
Is the smell when just sitting and engine off or primarily when the engine is running?
I ask because there are often return diesel pipes from the injectors that feed back to the tank. It has been known for these return pipes to become dislodged.
I did see a YouTube video about dropping a fuel tank. Can't remember which model though.

But I'm sure others will have more helpful responses.

If it only happens when full I'd stop filling it n stop worrying! After 15k miles you must have some idea of how much is needed to fill her up at any time. Knock 5 or 10l off that and Bob's your uncle!
Diesel fuel leak when tank full problem
Hi, I have a 2016 Ducato 180BHP Panel Van Motorhome. Now done 15k miles. When I have filled the tank, when the van is driven and in particular, on a slope, diesel is leaking from somewhere high up in the filler. Is there a breather? I stop filling as soon as the pump clicks off and don't overfill. The garage who serviced it last and did its first MOT, examined it but could find nothing wrong. They simply suggested it was overfilling that had caused it. Certainly form underneath it is not possible to see anything wrong but I don't want to go to the bother of dropping the tank unless I have to. Can anyone suggest what the problem might be and where exactly fuel might be escaping.
Apologies if this has been asked before. New to the forum but guess I should do a search too.
