Replace PS lines when doing rack swap?

[Mook613]

I am going to put an E46 ZHP rack into my E30.
All seems pretty straight forward, except for the PS lines. I've read that the original lines have to be bent just slightly to match up to the in/out on the E46 rack.

Is there any reason to order all new lines, or specific lines?

I will be replacing the reservoir and likely the low-pressure lines.

The reservoir is actually a maintenance item and is cheap and the low pressure hoses always leak so these are good to replace. As for the high pressure lines as long as they look ok you're better off trying to tweak them to fit.
