I have two pre made lines (a little over 2 feet long) with fittings , 2 90's and 2 straight -12 AN.
I believe these were made to be valve cover vent-lines but they can be used for anything else. The are new and include the -12 Bungs.
The fittings and lines would probably cost you $100+ if you were to buy em new.
My asking price
$70 because I have no use for them.
Here's the lines I have:
There's two lines there, the second one is hidden kinda, sorry for the bad pics.
