I'm needing to run some Seafoam through the manifold(?) system. I've added it to the oil for cleaning and now I need to do the other.
Well...from what I've read, you can use either the PCV hose or the brake booster hose to suck the stuff in...
Problem is...I can't make heads or tails out of all those hoses.
I see the diagram sticker on the left front under the hood...but that does not help much.
Is the brake booster hose easier to get to? If so (or not)...can anyone describe where exactly the hose to use is....and...once located...which END I disconnect to pour in the SeaFoam?
Any help greatly appreciated.

Here are the generic instructions :
With engine warm, slowly pour 1/3 to 1/2 pint through carburetor or throttle body throat. (If vehicle is port injected slowly pour SEA FOAM through direct manifold vacuum line that will feed all cylinders, possible sources are P.C.V. valve or brake booster line.) This will pull SEA FOAM down on top of the pistons and to the back of the intake valves to dissolve carbon. Turn ignition off. Restart engine after 5 minutes. If severe carbon build up is apparent, use more Sea Foam as previously directed. Make sure exhaust is well ventilated when using Sea Foam in these various ways as fumes will be extreme for a short time.
Pour 1/3 to 1/2 pint into oil crank case to clean rings, lifters, dirty parts and remove moisture.
Pour 1/3 to 1 full pint into fuel tank to clean injectors, carburetor jets, fuel lines and remove moisture.
Thanks for the feedback. I gave it a try a few days ago....easy as pie....after I knew what to pour where.
Couldn't help but feel a little nervous at first...pouring flammable liquid down a vacuum hose.......it stalled.....waited about 20 minutes.....held my breath on restart...but it cranked right up. Smoked like a dog....putted around in Low gears for a minute then took it out on the road.......looked like a yayhoo driving around an oil burner....but it cleared up after a few miles......came back and changed the oil for good measure (I heard it's a good idea to change the filter afterwards).
