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 differen

ce - no issues before either. Can anyone confirm that this should be connected? Thanks!

Maybe someone could check on theirs and see if its the same?

Mine is set up differently (diesel), but I would assume that this is the vacuum feed for the lockers.
