I have taken the advice and done the following. Inspected all joints, everyone is like new. Pushed a piece if wire down the vent pipe, It went through from top to bottom. The only thing was the was some fluff on the end of the wire which looked like an insect cocoon. I then went and filled up and checked whilst filling. No leakage, no spil nothing. Then drove round left, right, stop, start, to swill the petrol nothing. No smell. So what now.?
By the way there is no fuel filter on the vent pipe as shown in the parts manual. Page 21-81 152691

I can only think that the vent pipe was slightly blocked with this moth or whatever cocoon.

A bit of long shot, but could the now cooler weather resulting in possibly less pressure in the tank have anything to do with the fact there is now no loss of fuel? As we know, fuel is very searching and higher temperatures will cause higher fuel pressure in the fuel tank (which can be heard with the hiss when the petrol cap is released), so as it is now cooler there theoretically will be less pressure which may have self righted the problem for the short term.

Is the fuel smell definitely inside the car or possibly on the outside? What kind of fuel filler cap is fitted? The original twist type cap for me seal the best, and I use them on all my Triumphs, but the aftermarket locking caps with the cork seal were notorious for leaking. The design of the filler neck was poor anyway and fuel regularly leaked from a full tank - that is why Police Triumph 2000s in their day (in Lancashire anyway) did not have the rear nearside wing sprayed in the orange dayglo paint, as spilt fuel used to take the cellulose paint straight off.

As I filled up I had the boot open and the back bording removed. I stuck my head in the boot and had a good sniff. There was absolutely no smell of petrol. I have a bayonnette locking cap (I think it is French god knows why) . I have never noticed a vacuum in the tank when undoing the cap. I know the sound from my wife's car. The pertrol smell was when one quarter light was open. Admittedly it was a few degrees warmer a normal Autumn day which gets cool at night.
The only time in the past was asmell of petrol was when the rear carb float stuck. That was the first thing I checked on the roadside.
I do have problem filling up if the super gagets in the nozzle are set up incorrectly and the back pressure is wrong. I found in such cases it was quicker to use the reserve canister a couple of times and then go to another petrol station.
