I've been working on the car while stuck at home with all the COVID-19 stuff going on. Getting to some projects I've had on the list for a long time as well as going through lots of parts boxes. I have some fuel hose I need help identifying.

It's just a length of black rubber hose, maybe 2 feet long. I don't recall what kit it might have come in or whether I bought it on its own. The markings on it indicate:

NBR/CR 03/10/51 05:30

And then on the opposite side it says Made In Germany.

I am wondering what these numbers mean? I found NBR/CR on the Internet and it means:

"This fabric-reinforced fuel hose is made of the material NBR / CR (butadiene acrylonitrile rubber / chloroprene rubber)"

I suspect the numbering is in Metric and tells me inside diameter, outside diameter, length (perhaps, although irrelevant if cutting it to desired length) and also what pressures it is rated for, likely in Bar.

Anyone know how to interpret these, or have a legend perhaps?

I found a picture of a parts order from ~2011 and it turns out that hose was one of the ones included in the fuel accumulator kit I got.
