Sunroof removal

Do the drain tubes just pull off the cups?

Mine feel as if I will snap the plastic if I pull on them

They should do, but age hardens the pipes and the plastic goes brittle, so chances are you may bust one. But it's better it breaks with the headlining out than just after you put it back in again!
You can get replacement sunroof drain corner thingies with the stub tube on to repair one, if it comes off in your hand. A bit of Bic Biro also works...!

Ah can you?

Where from?

I've had the headliner out for weeks with the intention of removing the sunroof and resealing but the thought of snapping the plastic and ruining the cup bits puts me off!

If I do snap them I can use a biro?!

I had a chap out to do the sunroofs on my first D2, and he glued in a section of Biro where the spout had snapped off, but I think the inside diameter is a bit smaller that the original tube, so you could probably find something better!
Just had a quick look and found this:-

It's the whole kit, but you can see the corner pieces there. I'm sure I've seen them on their own though.

Some here. Not cheap...

Slice the hose with a Stanley down its length on the pipes and peel it open to get it off. Get some hose same Id as original and a bit were it's I'd is the same as original od and make a connection (sealant) if there's no slack available.

I used a piece of this aluminium tube and bonded it in with jbweld. https://www.ebay.co.uk/itm/192444024581?ViewItem=&item=192444024581&var=492455496739
Double check the OD though.
