I want to do a CRC valve treatment and want to be sure I’m spraying in the correct vacuum line. See attach3d photo of my engine compartment. if it’s NOT the hose I placed an arrow please let me know the correct hose
To use. I tried finding the answer on my own but no luck.

You want to spray it into your intake manifold, which is the lower center of your pic.

That might work, it's pretty small though. The vacuum line you originally circled off the brake booster should logically go to the intake manifold but I don't know if it's a straight shot or branches off places where you don't want the chemical.

I'm pretty sure some guys have pumped it in upstream of the throttle valve at that purge line connection on the intake hose.
