G500 disconnected vacuum line

Hello,
2004 G500. I noticed a disconnected vacuum line at the top rear of the engine. It's a hard vacuum line coming from below near the firewall. It appears to connect to the check valve that I know have it connected to (arrow in pic). When disconnected, the check valve had vacuum leaking - it sucked on my finger. I connected as shown in the pic. I notice no drivability difference - no issues before either. Can anyone confirm that this should be connected? Thanks!

I can't really see the line that's disconnected, but those are for your locker system. Is there a connection to re-connect it to?

The little filter things facing downward aren't supposed to be connected to anything, if you're wondering.

Thanks pulunm,
The picture is not great. I reconnected the line that the arrow is pointing to. it was previously hanging loose. It is now connected to a rubber nipple on that white check valve to the left of the arrow in my picture. The large line that that check valve is in is the vacuum line from manifold to brake booster.

Also - understood about the locker lines/filters

Anyone willing to walk out into your garage and take a pic of the same line on your car so I can compare?
