Need some clarification on Seafoam
 

So I searched and found that the procedure for decarbonizing the engine is to suck the seafoam out of a cup or something driectly into the vac hose. I'm just not too sure where this is located, can anyone point me in the right direction with some pics? Also, I was going to add some to the gas tank, is there anywhere else I should be adding it?

Sorry for acting like a smuck, but I've been without my 7 for quite some time and it's finally out of the tranny shop and I want to do everything I can to get it running in tip top shape.

We use a couple of methods at my shop. One is a BG system which is simply a can that has a special adapter with a line that goes into the throttle body and gets sucked in with the engine running. And the other which is the manual way is to get a can of carb cleaner and spray a shit load into the throttle body and immidiatly start the engine up while holding the accelerator down so that the engine wont stall. Both methods are laughed at by the master techs at my shop and they say there just ways for service to make more money. Its realy not going to make that much of a diffrence.
Which ever method you choose keep in mind by doing this your releasing a bunch of crap into the engine and with a rotary and there seals there that much more delicate to crap being in the combustion chamber. So whatever you do do not let that shit sit in there and dry up. Make sure you get it out as soon as possible while its all still wet in there.

there is a write up on the rotaryressuresction site about this, it goes like: hook a vaccume hose to the UIM and stick it in a gallon of whater, let the vaccume suck the whater out
