Fuel Filler Pipework to Tank
Ever since I installed the evap system (its always smelled a bit in this area anyways) i've had a petrol smell in the cabin when left parked or driving with window open. If driving windows shut and blower on like normal, there is no smell however. The smell when it does happen is worse now with E10 I think.
I've decided to have a go at curing it and wonder what other folks have done in their cars?
My current setup is pretty much as per the manual;

Built pretty much as the manual said & based on the limited knowledge we had back then (2000).
Aero 400 cap - short hose joiner - Metro (IIRC) pipe - metro bellows joiner - more metro pipe - metro bellow joiner - tank neck. Off the first metro pipe is the large hose to tank vent with a smaller hose going up the pillar for a loop and then originally out under the car open to atmo, but now goes to evap canister.
The larger vent hose is actually marked "heater hose" and came with the kit IIRC - maybe not ideal for fuel! The rest are/were OE fuel system hoses/parts.
Here is my thought for revising it, eliminating as many hose to pipe joins as possible and using proper wire reinforced* unleaded-proof hose.

*needed to stop kinking in the sharp bends but does however cause issue of being less flexible.
I understand JB weld to be fuel-proof and this was my original idea though further pondering made me wonder if such a part would make removal of fuel tank hard/impossible in future. The part would have to go through the tub and then turn to face upwards with enough length to allow hose to fit securely. Hence my idea using orings and a clamp thereby allowing it to be removable. This may all turn out to be not needed if i can just get the hose to shove on as is.
It's this (likely structural) section of the tub that means the hose cant' fit on the tank outlet at a 'nice' angle.

Why install evap system? Well i thought it might help with the smell (no!) and also it extinguished the MIL so that I can now have the MIL LED connected again as a usable problem waring indicator. Also - polar bears etc.
