Type 44, NLA fuel line conundrums

[DeWitt Harrison]

I've lately become paranoid about the eleven flexible fuel lines
(injectors, main supply, warmup regulator, etc.) in the MC1 engine
compartment which are all NLA according to one Denver area Audi dealership.
So I thought that they could perhaps be rebuilt with fresh hose stock.

But having dissected one old Audi fuel hose, I'm currently of the opinion
that it would be a formidable task to rebuild these fuel lines to factory
spec because, after extensive surfing, I've learned the oe hose is a very
specialized construction and dimension with a nylon 12 core and a braided
steel reinforcing covering. It also appears that special tooling would be
required to assemble the hose to the hose ends (assuming the non-standard,
oe hose ends can be salvaged from used factory hoses). I do not think my
local hydraulic hose fabricator/rebuilder would be up to the task.

So ... any thoughts? Am I being too paranoid about these 28 year old fuel
lines? Are there hose fabricators who could rise to the challenge of
rebuilding to Audi original specs? (If they were simple rubber fuel lines,
replacement would be trivial, right?) Or would it be smarter to rip out the
whole CIS system and go with contemporary EFI?

Thanks for your ideas,
