I used this to upgrade the plumbing into my ZL1 lid. Initially I was planning on running 12an fittings directly as most of my friends have done. The problem with doing it that way is 2 fold. It makes it hard to fill and fully purge air out of the system even when you have a separate reservoir as the Brick is always the highest point in the system. When I found this product I knew it was a must for me.
I recommend this product
Great product amazing quality.
