So I've been reading about the magic of Seafoam so I figure I will give it a shot. My truck has 112k miles and I am about to embark on a 3.3k mile trip. I'm just not sure which hose is the vacuum hose. I looked on Youtube and searched on here and no one specifically shows which hose.

Red or blue?

I seafoam'd today. I just put it in the brake booster vacuum and the gas tank, since I just changed my oil a week ago. I got lots of smoke! I will keep you updated if I notice any difference with performance or mileage.

I think that's just if you put it in the oil.

I would assume it is good, meaning you don't have much gunk build up in your engine, but I could be wrong. On a side note, is there such a thing as too much Seafoaming? I was thinking that since I don't know my truck's past history I would Seafoam every oil change for about 4 oil changes then go to every other oil change.
