A query especially for our Dutch aficionados: where can I find 5/16" soft copper tubing plus fitting for the oil pipes of my M20
I googled till I saw stars but no 5/16" copper pipe...

I seached in Amazon and found this immediately (German)

7.9mm is 5/16"

8mm copper tubing is available at most good plumbing stores, I use it all the time, though sometimes you need to drill out fittings/unions to suit before soldering.

I use this firm here in UK. Lots of other interesting stuff in their catalogue.

Thanks guys, for the suggestions
But I found everything at 10km from my home: a caravan and camper shop, they use that 5/16" stuff for propane heating installations
