Hi Paul and welcome to the forums and club!
As a petrol engine owner I can't give a lot of advice on the source of the fumes but a few things worth looking at are the fuel lines themselves (ie, are any of them looking worn at all?)
Could your tuning set up be malfunctioning somehow and providing the engine with too much fuel? Any unburnt fuel could then be lingering in the exhaust fumes and this is what you could be smelling?
Hopefully a CDT-minded person can help you out in more detail... :lol:
