Contrary to those who haven't a clue and wanted to ridicule your question, the answer is YES. The German Luftwaffe had extensive mid-air refueling capabilities as well as towed fuel cells and winged fuel drones. The 1st operational refueling plane was a modified HE-177 A-1 and was fitted with the flexible MK 101Z mid-air refueling gear, this happened on Dec 23rd, 1941.
Over the remaining course of the war, many more planes & types were outfitted in such a manner using various types of gear of which i know of at least 4 different types.
If you would like to learn more, i recommend you get the book "Luftwaffe Over America" by Manfred Griehl
ISBN-13: 978-0-7607-8697-0
ISBN-10: 0-7607-8697-6
This book deals directly with your question & has alot of pictures, technical drawings & specs.
For you other "Tools", try turning off the History channel & pick up a book to get some real knowledge into your puny heads.

This is the first time that I have ever heard of a Nazi inflight refueler.
I spent 7+ years as a KC-135 pilot. History as we were taught was that the early experiments were in an American plane called the 'Question Mark.' I just looked online and I just learned that the British were working out the technical details. Other than the book that you are recommending, I have seen no indication of a Nazi inflight refueling program.
There was no militarily significant inflight refueling during WW2. For someone so proud of their intellect, you need to research the word 'operational.'
