Ooooooh, you know what else? If you still have a pending order that you haven't placed, or that hasn't shipped yet, get some real barbs. I completely spaced on this earlier, but those plastic pieces of crap that Swiftech uses are the second biggest black mark against them. I use 1/2" OD Fat Boy barbs with G1/4" threads. Swiftech uses BSPP threading on their stuff, but the threaded portion of the barbs doesn't extend deep enough for this to be an issue; the o-rings will seat just fine, just make sure that you don't have tubing torquing on the barb and you won't have any issues.
Will the 1/2" OD Fat Boy barbs with G1/4" threads work with my stuff and how many will I need? Thanks
