Fuel pipe

Hello, I have a problem with the fuel pipe, it is the No. 8 in the following drawing that forms an S.
It has hardened over the years, and presented a slit.
Its production has stopped and is no longer available.
I want to replace it with silicone fuel pipe, but I am afraid that at the points it turns it will reduce its cross section and I will have a problem.
Has anyone tried to replace it with a commercial fuel pipe? Do you have a solution?

Standard commercial fuel pipe should be fine https://www.ebay.co.uk/itm/Nitrile-Rubber-Smooth-Fuel-Tube-Petrol-Diesel-Oil-Line-Hose-Pipe-Tubing-Breather/130740225601?var=430086075654&hash=item1e70b98641:g:ITQAAOxyOalTX6Br

Because the pipe forms an ''S'', I'm afraid that at the points where it forms the 90 degree voice, it may crumble and not allow the right amount of fuel to pass because the diameter is reduced.

I will look for pipe of this type and construction material because unfortunately this item doesn't post to Greece.

I have another problem that came up. Removing the old tube, it had stuck to the end connected to the carburetor and came out together with the piece of brass tube that is normally firmly glued to the carburetor.
Now I have to find a way to fix it at that point. Maybe with some adhesive that is not damaged by gasoline.
Maybe with thread glue?

PVC tubing of same wall thickness should be OK, soften it in hot water before you fit it. As for loose tube, maybe best to make up a threaded one and tap out carburetor body to fit.

I will think about it, because it is made of soft metal and I can not use a hammer with force.

Today I went to a spare parts store to buy a fuel filter that I have placed after the tank, so the rust it has inside not to reach the carburetor.

There I found a very good quality pipe in the same dimensions as the original pipe.
Hope somehow i will be able to turn this the way as the original.

Will be fine if thick wall tube (around 5mm id x 9mm od), it will take up the shape of the old one. If its a bit stiff just heat it up in boiling water to soften it before fitting

Ιωάννη (= John ) This is a black silicone tube, if I can not place it in a ''S'' shape then I believe that it will definitely be able to bend in an open ''Z'' shape.

Although I have completely restored my motorbike, every time I do not find a spare part I feel bad to place commercial spare parts.
not only because I do not trust them with quality but because I do not want it to differ from its absolute original form.

I recently noticed a fuel leak in the fuel switch (35T-24500-00 FUEL COCK ASSY 1) , I really felt very good when to my surprise a genuine spare part was found in the Netherlands with the help of the Greek delegation, with 33 euro including delivery costs.
