WTBurke, thanks for the reply, I currently have the 1/2" version mounted between the draw straw and my FASS and need to find one for a friend, I got the last one from Vulcan, but he hasn't had the larger 1/2" version for a while and I'm looking for another source. The one in the picture is the 3/8". I just can't follow the logic of a1/2" draw straw, 1/2 lines, and a 3/8" pre-filter, maybe if you're adding to stock system, but an upgraded big line kit.
