Guys, looking at the image below, there is the vacuum line from the plenum, down to the valve cover. The valve cover end is circled in red. I am confused as to whether the circle is where I disconnect and then the seafoam travels up the hose into the plenum. Or, I disconnect up top at the plenum and the sea foam travels down the tube into the valve cover.

I know about the 3/16 tube and slowly sucking it in. I am just not sure which direction to go on the hose.

thanks!

 

i would remove the vacuum to the booster, which is the red line in top of the plenum

 

So, disconnect at the brake booster end, feed Seafoam through hose going into plenum via the brake servo valve hose (red circle).

that the best and safest bet?

 

I'd just connect it at the red end and spray straight end. If you connect it at the booster end then you'll have too much distance and not enough vacuum to pull the seafoam.

 

connect it at the plenum when you remove the booster hose by pushing in on it.

 

OK, so the 2-feet of 3/16 hose has one end in the can of sea foam, the other end going into the red circle, pliers crimping hose, controlling flow from can into the intake?

 

there you go, film on utube
