I've never fed Seafoam through the throttle body vacuum line, always the brake booster. How do I do this? Do I connect a line to the throttle body and have it suck that way? I tried using the line that connects to the throttle body and it doesn't even suck. I disconnected the line, added a T, and a longer piece of vacuum line. I noticed the spout on the throttle body making a sucking sound so I'm guessing I connect the line to that and suck it through that way, but that would be just like pouring the Seafoam down the TB. Anybody know?

Found my answer. Thanks!
