Rear fuel tank overflow-breather

[Steve kay]

Surely I am not the only person who watches the petrol gauge, and stops filling when it begins to look pretty full. I have learned a polite response to the daily passer by whose grandfather/father /other relative had a Seven. Just say hang on a minute. Failing to concentrate on the gauge allows one to keep filling until the gentle flow of petrol from under the car demonstrates the breather overflow.
