There is a carbon chamber fitted that condenses fuel vapours. There is a pie that vents from the carbon trap down under the engine bulk head and to 2 'connections' clipped to the chassis rails close by the gearbox crossmemmber. Your smell may be coming from on of the vent tubes broken/perrished or missing. Check the full run of the tube. The carbon trap is close to the rad at the front on the turbo side of the engine.
Large, black, about 70mm diameter and 150mm long.
