I've replaced one of them on my 220D with standard fuel line and a couple clamps. Not worth trying to get the original, as it isn't available anymore as an aftermarket and would have to be special ordered. The 240D parts were, but that was a couple years ago.

They will eventually get brittle and break if moved -- if you need to remove the IP or filter housing, plan on removing them carefully and be prepared to replace them.
