The webasto went fairly well. mostly just disassembly, cleaning, painting and plating.
The biggest pain was reinstalling it along with the tentacles of hoses. It took 3 tries to get it in with the hoses attached correctly, but now I have one hose fitting leaking and I ended up with the head on the clamp facing a bad direction, so I looks like I have to loosen and pull the whole thing up again. It is very tight territory in the bay once it is installed. Make sure you get all the clamp heads pointed to were you can access them later. It took me most of a year to find the correct fuel pump for it.
I have not actually fired the system up yet, but did for a few seconds turn the clock knob and I heard some fan sounds coming from the unit, which is a good sign. Each separate component of the system tested good, so I hope the entire unit will work. I still need to test that I have the fuel pump connections correctly and that it is supplying fuel to the system.
