My nova has the fuel cap situated in the B pillar and i constantly have the smell of petrol in the car. There is also some leakage around the cap and the smell gets stronger when i break hard so iam guessing that the petrol is all running up the pipe towards the cap.
I know that there is a ball valve to stop this and that mine has obviously bust but i went to vauxhall and they reckon you can't buy a ball valve. Any ideas anyone?????
