CBR400RR fuel filter to fuel tap line

Hi all!
I was swapping some spark plugs out today and as I removed the fuel tank, the line from the fuel tap to the fuel filter perished, fuel everywhere….
Having now swapped the spark plugs I‘ m on the hunt for a replacement fuel line but can’t seem to find one anywhere online, an idea where I can source one?
Number 7 in the exploded diagram for reference.

thanks in advance and ride safe!
