Fuel pipe

Hi all I have noticed a strong smelll of petrol form my bike and the feul hose was quite wet, so going to replave it however it seems to be 2 different sizes joined together, Is this correct and if so does anyone know what size the hoses are? Thanks Wayne

This comes probably too late, but for some reason Honda decided to make the pipe with different sizes in the ends, maybe like 8 and 10 mm (not sure though). I managed to get original part couple years ago, not sure if they are available anymore. A job for machinist to create and 8/10 mm thingie between pipes.
