Should I drain the radiator before removing one of the fittings?
I'm going to be doing these fleece lines on my LB7.

No coolant does not need to be drained. Also the fleece comes with really good step-by-step instructions only. You can view them here. fleeceperformance.com/media/wysiwyg/FPE-2019-26_FPE-TL-LBZ-LMM-LB7-LLY.pdf

Quick question, are these routed differently than stock? I have a leak in a crimp on the upper line and not sure it is routed this way in stock configuration (just by a quick look under my LBZ), thanks.

I believe they are routed the same. Go the fleece performance website they have good online instructions and pictures.
