Its a valve that it plugged into the valve cover on the passenger side of the engine. If you pull it out of the cover you'll see that it is a pcv valve. It should be the only hose going into the cover. You can then pull the hose off of the pcv valve and use it to administer the seafoam.

ok so just to make sure.. on the passenger side of the truck there is only one hose going into the value .. i pull that end out and into that end of the hose i can pour the seafoam..
aside from seafoam, what you do recommend i do, let me also add that right after the seafoam I am installing new plugs ..anything else i am overlooking.

In order to seafoam I would normally pull the cable off the brake booster line, I've never done it through the PCV hose.
1. Seafoam
2. New Plugs
3. New Airfilter
4. Clean MAF
5. Clean Throttle Body
6. New Fuel Filter
7. New PCV Valve
8. Change fluids over to synthetic (Engine/Diffs/Transfer Case/Transmission)
All of the above would assist in restoring previously lost throttle response.

You can use any hose that pulls vacume to put Seafoam in your engine.
I use a smaller hose connected to intake manifold & add 3ft. of vacume hose so I can slowly feed the liquid in to engine without having the engine kill because of a major vacume leak. I just pinch off the flow when the engine wants to kill out. I also don't like to race the engine speed with a major vacume leak as I'm old school and afraid of running too lean and I fear burning up a valve during the process.

The two biggest things for throttle response and MPGs on the V10 are cleaning the MAF and changing the fuel filter.
BEFORE you go and pour a solvent into the intake of your somewhat-perfectly-running engine, go and do all the normal tune-up stuff first.
If you're afraid to do the plugs, at least remove the COPs, make sure there's no moisture or dirt in the holes, and check the boots. Then use dielectric grease around the tip of the boot where it meets the plug, the top of the boot where it seals to the COP and then around the seal area where it seals to the head.

There's something wrong with the system, and it's double posting, but it's only been doing it for a week or so. I didn't get over 20K by double posting
