Volkswagen Golf Mk1 - Diesel (CK Engine) Hose Sizes

[GTI14L]

Just looking at replacing some hoses in the engine bay on a Mk1 Golf Diesel with the CK 1.5L engine.

Looking at the following hoses
- Vacuum Pump to Engine Block
- Fuel Line to Fuel Filter IN
- Fuel Injection Return to Fuel Line Return
- Injector Pump to Injector 1
- Injector to Injector

Does anyone know for certain what the internal diameters are for the above hoses (each possibly being different).
Also does any know of someone who has the Cotton Braided Diesel Hosings for a decent price?

Any help will be appreciated.

I've got PIRTEK onboard as a sponsor for my $hitbox Rally car, they said they'd happily check over it and replace anything that needs doing, at least at cost, I'll get details of what comes out / goes in when they do
