MOA #24991, south of Los Angeles
If that's actually 4.5 millimeters (where in the fiche is it?? sounds small...) - that converts to 0.17716848 inch, so 11/64 " (= 0.171875") or 3/16" (= 0.1875").
And of course make sure it's rated for "injection" usage, for the higher pressure than with non-injected (carb'd) systems.

MaxBMW shows the line as 8mmx13mm, part# 16 12 1 180 409 at about $45/meter. #9 in this diagram.
The 5mm x 8mm tubing is for the rain drain and charcoal cannister lines, #1 in this diagram.
Best,
DeVern

GSAddict once again shows his expertise! I can confirm what he said is right as it is exactly what I used to replace the external fuel lines on my R850R.
5/16 inch internal diameter SAE30R9 fuel injection hose is available by the foot at most auto parts stores, most often made by Gates as part of their "Barricade" line. From most O'Reillys stores it's $7.49 a foot and you need just under 5 feet.
However, if you're ordering anything else from Beemer Boneyard, their universal BMW fuel line kit is $28 for 5 feet of equivalent fuel hose and comes with hose clamps. I haven't yet found a place that beats that price and they also offer a 10% discount to MOA members.

Pay close attention to the different spec for internal (in the tank) fuel lines. These are not as easy to find but don’t be tempted to just use the other one.

Yes that is what I was trying to draw attention to.
In Georgia at three automotive stores Autozone, O'Reilly's and Advanced Auto didn't have the R10 submersible hose. They had the external hose. Two of them had no idea what I was talking about
So I ended up calling Max on the phone and got the good stuff
. My initial confusion was that I was looking at the wrong hose

Much the same on this side of the border.
One parts man even went as telling me there was no difference.
