Ok, after spending a good hour or so faffing I found the following.
1) The rubber O-ring actually fits snugled around the body of the fuel filter housing just above the threads.
2) There was one already fitted, I just didnt see it (or look tbh) for it be in that place.
3) So its fine and was air tight.
4) Its a bloody pain getting that lid sqaure.
It's running fine, idle is spot on so I assume everything is fine.
It does seem to be getting a little bit better and doesn't start any worse then the misses 90HDi.
Next on the list for next months pay is Drop links & possibly new front discs and pads depending on cost.
