If you decided to go this route , I have some red and black chan fittings for that size of hardl line . 3 packs of 4 ready to go , brand new , un used . I will sell for cheap. $50 for all of them .I ended up going a differnt route in my build , or i would have used them , just like mentioned above , they are the best secure hardline fitting around , that is why i wanted to go with them .
