G'Day Guys,
This is a good news story.
I have been suffering from a fuel smell only noticeable when reversing with the drivers (RHS) door open and was expecting to have to drop the tank and check vent hoses.
Checked around the filler one more time and finally found this:
The big hose clamp on the left is the filler pipe.
I have to say it was a pain to get two hands into this area to replace the rubber hose but as usual, you get there in the end.
Overall, very happy that I didn't have to drop the tank.
