Check valve under sjp

[jacobsen]

Which direction should the Arrow point on this check valve? The big one on the left side of the sjp that runs to the little metal hose on the left side of the valve cover to the turbo inlet pipe.

All check valves should flow toward the intake manifold.

I should point out one exception. The check valve on top of the air box flows toward the TIP.
