Hi guys, I want to do the Seafoam vacuum line treatment to my 1997 4runner, 4cyl. I just bought the car so I don't know my way around it too well. Here is a snapshot of my engine. Just let me know the letter and color of the hose im after. thanks!

Here's a quote of when I did it on my 2.7

3RZ 2.7l OWNERS:


DO HALF OF THE TREATMENT USING THE BRAKE BOOSTER LINE ON THE INTAKE MANIFOLD. Then, if you look on the other side of the intake manifold, you'll see another vacuum line on the opposite side. Use this to finish off the last two cylinders.

D it will give you the most even distribution among all cylinders. The brake booster line will only feed cleaner to the front two intake runners.

I used the brake booster line, it worked well for me.
