'99 what vac line for carbon cleaner?

What vacuum line should I wse for the carbon cleaner to be sucked into the engine?

and where is it?

5.7L.

thanks.

If you have vacumm booster brakes (not hydro-boost) you can use that line. Also you could use the PCV line with the valve out.

Does the pvc valve get it to all cylinders?

I can't find a vacuum hose out of the manifold.
