Methanol doesn't like rubber. Maybe that's why. I guessing. I don't know for sure.
 
I use the clear line because I can see any bubbles if they are there, Bubbles to me says that air is getting in some how, and I sure don't want any extra air inside my Dual Buller billet carbs on my Sudam stroker at 14,500rpm's.
