I am not a hydraulic engineer, which is probably just as well. Having put on the thickest gasket, I thuoght that I would try the thinnest. And yes, that has stopped the cascade of petrol onto the exhaust pipe. Obviously I had misinterpreted the relationship between top of float and button on the valve. Is this what the modern chaps do when their in car screen flashes and says computer failure? They go to the workshop, get down a box labelled “chips” and swap stuff till it works? Why a washer would work perfectly for many miles and then go wrong is a puzzle, perhaps attention seeking behaviour. Many thanks to all.
