    Fuel tank thread size?

    Anybody know the thread size for the outlets on a coupe fuel tank? I need to get some adaptors like Mr Tonks fitted and he can't remember the size.

            For future reference it's M14x1.5mm on a 3B tank

                    The fuel rail connections are Bosch M14*1.5 which I think are the same at at the tank. I've used these several times and they work well: https://dynamicfluids.co.uk/ols/prod...r-bosch-metric
