if you follow the vacuum hose that heads down toward the bottom of the photo, you will see the check valve in its proper alignment. make sure both of those vaccuum tubes are properly connected as well as the check valve.
With your AEM, the tubes won't look "quite" like in the picture since the tubing loom is gone but note the white check valve in the picture. This is the proper direction it should be in.
Go to the beginning of the two tubes where they plug in near the intake manifold. One is on top of the other. Follow the top one down to the check valve. From the check valve, the tubing continues down to the passenger side of the black plastic cannister that's mounted on the frame cross member. The other side of the cannister has another tube coming out of it and this one runs to the "outboard" connection on that black valve thing (the one with the wiring harness on it) that you mounted on the side of the AEM pipe (you can see this in the highlighted part of the picture). Then there is an "inboard" tubing from that valve assembly and it runs to the "bottom" fitting near the intake, where the first tube began.
