Hello men & women,I am trying to finish this a & a drive & I don't have a PS cooler ,so the high pressure side is good, that came with the kit ,the return is another story, I tried using a barb ,it tightened up that's the 16mm return side ,but the metal line even though it was tight in the rack u could turn it by hand I may have to put a chaser in it & or try using a an fitting like what it came with on the kit, I don't have the PS cooler anymore & was trying to find a quick fix, so what do y'all do with the return side of the PS system line from the rack to the resivior?
