Look at the clock position of the tabs between the product @ShagginGSW received and the examples @El_bigote_AJ posted. The tab that should be almost directly across from the arm is not close on the one shaggin received.Because if you rotate the TIP so that the front of the arm are parallel the tabs would line up. That’s how it would be when installed.
The picture of the elbow installed shows it is correctly installed, the port for the PCV line extends nearly straight up when the elbow is clocked into the final position. If that elbow continued to rotate counter-clockwise to engage that other tab (not possible since the securing arm won't allow that to happen) the port for the PCV would get close to interfering with the plug for the DV.
