Your best bet would have been to buy cunifer line from NAPA and a bubble flare tool from amazon - the cunifer line bends like squishy candy and it will never rust out either like the factory mercedes line.

you can also buy the nuts from autozone etc. for bending the line first get it straight then use the bending pliers from harbor freight. Remember that you are bending tube, you will end up with some tubing gain
