Hello Moped Army, and thank you in advance for the help.

The quarantine means I get to spend time with both of our old FA50s (I'm thrilled, it's way overdue).

I need to replace the fuel / oil lines on both. I'm sitting here with my FA50 service manual but for the life of me can't find the fuel/oil line sizes.

If any of you know, could you tell me the sizes of the lines please? Inner diameter and outer if possible? Or... part numbers if you know them?

Also... if you've got a reliable source for the lines, please do pass that along. Thank you very much.

Why do you think you have to replace the hoses ? Are they just a bit limp or ???

If that's the case , leave them be . Mine have been so for at least 10 years and still no leaks .

You'd do yourself right by bookmarking this :

It answers your questions .

Note : I would not replace the oil feed hose from the pump to the case , if they don't leak .

Thanks for the reply, and the links. Good stuff.

Glad your lines are solid.

The lines on these two bikes are original - 35 and 36 years old. They are showing a bit of their age (cracking and a bit brittle).

I'm doing some carb work and want to update the lines at the same time.

Thanks again.

Check with your favorite auto parts store .

They might have 6mm fuel hose in bulk .

I just brought some fuel line at a chain saw shop. I like the see-thru stuff.
