^ just use a cleaner and a clean rag to wipe all the gunk out.just did it to mine.
Just to give everyone a lil info on this proceedure: I used to put a bottle of Sea Foam in my gas tank about once every other month. The first time I put it in my fuel tank and started it it caused a black cloud of filth, and the engine kept wanting to stall out if I didnt keep my foot on the gas. After about 10 minutes it smoothed out and ran great. About 90k miles later (at around 250k miles total) I broke a timing belt. I pulled the head to check everything and put in a new head gasket. When I pulled the head everything in the cylinders was crystal clean. I had a couple small spots of carbon build up on the piston heads no thicker than a sheet of paper, and the valves were smooth and clean. So yes, this stuff really works.
Sidenote on the warning of adding it to your oil: I wasnt aware of this risk, and several times I have added the Sea Foam to the oil, and ended up not changing the oil for months after. I have done this with 5 different cars, and have had no failures related to the proceedure. After reading this I wont be doing it again until right before I change my oil, but I wanted to relate my experience so that people wouldnt be too scared to use it in the oil thinking they basically have a timebomb on their hands.

You just pour the whole bottle into your gas tank? You post has convinced me to give it a try.
So was the engine running when spraying it in there? and you were working the throttle by hand?
Yes. I wait until my gas tank is just about empty, pour a whole bottle in, and then fill up the tank with gas. I feel that this is the best way to make sure the Sea Foam mixes thoroughly with the gas.
i just did it in the gas tank, threw the vacuum, and then i put some in the oil rite before changing it…seems to have better throttle response
