In 1970 my wife and I were out in Lincolnshire in our Frogeye ( We were doing a year at Cranwell courtesy of the RNZAF) when there was a sudden, overwhelming smell of petrol. Pulled in, checked under the bonnet and found that the thread in the fuel pump body for the fuel outlet pipe union had stripped. After a little fiddling I discovered that the stubby screwdriver from my toolkit could be wedged against the pipe hard enough to seal it in the pump. So off we went. Six months later I sold the car to a dealer, after it (and the screwdriver) passed MOT. I occasionally wonder what happened after the new owner found and pulled out the stubby.......
