Any tips on removing the turbo oil feed line on a 1983 300d? It's always something...

-Jacked car up to solder a broken wire on the transmission together

-Wanted to remove battery/tray to replace tray and fix water leak on firewall

-Fix leak

-Gut interior to dry carpets/remove water from floors

-Remove air cleaner housing

-Find that air cleaner housing bracket has broken at some point

-Remove/Weld air cleaner bracket

-Reinstall and crank car, pretty severe oil leak from back side of the engine

I'm guessing I broke the line somewhere where it runs along the back of the engine when I popped it off the turbo. How does one go about replacing/sourcing this line? Most info I found was on the oil drain tube not the feed

Thanks in advance
