Is Audi diesel fuel line the same as standard rubber fuel line?

For my 2014 Q7 TDI, the return fuel line (coming off of the passenger side injection) has developed a small leak where the line goes into a cylindrical plastic splitter/adapter. The line is about 6" long, and around 3/8 diameter size. Audi only sells the whole "part" which consists of 3 fuel lines and the splitter/adapter piece which connects the lines. Dealer part cost is $236 - which is crazy given the costs of these items is probably about $5 total.

If this is standard fuel line, I would prefer just to replace this 6" piece of low pressure fuel line.

Any guidance would be appreciated.
