After comparing the AMW catch can which I have used before on my Lightning, and the Elite engineering, I went with the elite. Very nice construction, similar to AMW, and the internal 'steel wool' is set up about the same way, although there is a difference in how it is captured.
I used these fittings to get to 1/2", from www.mcmaster.com:
91465-K181 - push-on brass hose fitting, barbed x male for 1/2" hose ID, 1/4" pipe size - quantity 1 (pack of 5) ($8.26)
50785-K42 - med pressure extruded brass thread pipe fitting, 1/8" x 1/4" pipe size, male x female 90 degree reducing elbow - quantity 2 ($3.20)
1/2" ID heater hose from Pep boys, marked "can be used for fuel and oil"
after swapping out the fittings, i attached the VERY nice aluminum billet bracket to the catch can and bolted it to the passenger side empty threaded hole in front of head (8 x 25mm bolt). Bracket fits exactly on Jeep and is quite a bit beefier than the AMW one I have used before.
