Hi having problems with my 990 superduke , what size should the fuel line be ,took off the tank fitted new line which is a 5/16 ,then found the tank had grown in size and had to be forced back in ,then ran the bike all seamed ok ,until fuel was dripping From the rear tank bracket,hard to tell if it was the fuel pipe or the bolts bracket area , the pipe is quite stiff so hoping that it is that ,got some more. Flexible fuel pipe that looks the same size as what came off as standard,but it will not fit ,bought One of then quick release connectors of eBay for £8 waste of money as it broke the minute I put pressure on it , any help much appreciated,
