Fuel pipe size 5mm or 5.5mm?

(1/3) > >>

billdn:
Thought I'd replace fuel pipe,so searched on here and found it needs I.d. of 5.5mm which I've purchased. However it seemed to push on too easily,  so checked diameter of fuel tap after little bump in brass connector and is 5mm , so do I need 5.5mm or 5mm, don't fancy petrol everywhere.  Could be over thinking it?!

Oddjob:
Normally 5.5mm Bill.

The fitting on the carb end is 5.5mm at the waisted center on a slight taper -  the built in olive is around 6 mm but it does seem that 5.5 mm pipe is a loose fit.
If you fit the pipe whilst the carbs are off you can fit a spring type clip.
I fitted mine with the carbs in place so had to use a narrow cable tie - for peace of mind even though the i/d is 5.4mm as its 1/4".

As they're not braided: prone of getting kinked?

Not a complex route from carbs to Petcock - original fitting has a steel coil outer cover. / heat shield
