1985 300 CD, I need to replace the clear/white nylon fuel hoses and the turbo boost pressure hoses that feed the ALDA. Do they sell these new with the banjo fittings? If not, do I just heat the new hose with a heat gun and force them on the old banjos?

Just buy them from the M-B Classic Center, they'll be cheaper than the dealer and will ship to your door .

Not answering your question but have used silicon vacuum hose for my ALDA line since 2007 with no issues.
Note there is no clamp on it as it only has to be able to handle about 12 psi of boost pressure. The hose also makes it easier to T in a gauge.

When I ordered a new Oil Pressure line from Mercedes the one that goes from the Block to the Fuel Injection Pump it came with 2 un-installed banjos that appear to be the same size as the one on the ADLA and a length of the clear plastic tubing.

To install it I taped the Jaws of a vice grips so it would not scratch up the Banjo face an a glove that has a rubbery gripping surface on it an simply forced the banjo into the plastic tubing. Some twisting helped.
Note I did not wear the Glove but I wrapped the glove around the line and squeezed on the line+glove.
The same could be done with the old Banjos and new tube.

Anyone reading this might also consider replacing their Block to Fuel Injection Pump Oil line while they can still be bought. I mean they are over 30 years old and ought to be brittle from the hot Oil going through them. That is why I replaced mine many years back.

That is good. I got mine from a Mercedes Dealer and they sent the tubing and the unconnected banjos. I can only report on what was my actual experience.
The pic I posted of the old and new lines the new one is the one I assembled.

This is one more reason why I avoid my local M-B Dealer : they don't know / understand older cars and have zero interest in learning .

They used to be O.K. then built a new building for the nevou rich and got rid of all the parts guys who knew or wanted to learn anything .

Plus, without exception the prices are lower .
