I decided to have a bit of an explore under the car to investigate petrol smells. Not those during driving, but a distinct smell I get when opening the garage door. Maybe it maybe not connected with this, I found a tightly kinked breather hose from the petrol tank ... the shorter of the two that has to make a tight turn on it's exit from the tank before rising through behind the taillight panel
Whether this is a cause or contributing factor to the smells I'm not sure, but it's clearly not as it should be.
Here is one solution - it requires removal of the entire tank and the install of a new pipe with the addition of a spring inserted to maintain some outward pressure on the curvature of the pipe bend:

I came up with another fix. Happened to have a hose holder off the back of a washing machine. I've got couple of these never used ... I guess you might have one knocking around too, or if not it's just a very cheap visit to your nearby hardware shop.
Here it is installed
Plenty of attempts failed. It's not an easy job. It ultimately took a little trimming to make it easier to fit, plus you can only work with one hand by feel. And that's if you can even get in there in the first place between the tank and the bodywork sill. Its tight and Ive got bruises. Those of you with big hands or meaty forearms won't manage I'd say.
But I like the end result after a couple of hours battle and nothing beats a low cost DIY innovation.
