Fuel joint PD 41A

[Sean_melican]

Hello all. I am doing carbs for the first time on my 1978 750K. The carbs are PD 41 A, not B, which appears to be uncommon. While taking them apart, I found one of the fuel joints has hairline crack. All three are pictured below. The largest is the one with a crack.
Looking online I can’t find an exact visual match, though text says they are the same.
Does it need repair or replacement? Can I repair it or does it need to be replaced?

Thank you.

Sean , they are just a rubber fuel line for the accel pumps . Go to you local and buy similar fuel resistant hose and replace

That's what I've fitted to the carbs I've overhauled R9 fuel hose of the correct bore cut to length will withstand any of the fuels around.

Those accel pump crossover hoses have a brass restrictor inside. Save the restrictors and insert them in the new hoses.
