Will seafoam overheat your manifolds if used in the tank?I would like to use it but worried about this and also clogging my filter.I only have about 43000 miles on her but she has set awhile in the past.I have had it for about 3 years and run it maybe 500 miles a year.This past year i havent ran it none.I dont have any fuel problems but think maybe the tank is dirty from setting before i bought it.When i had the fuel filter changed last year with the tuneup they said it was pretty dirty.I do use startron stabilizer often.

no problem you can run it in tank or suck it in through intake

Get the tank drained and cleaned.

I have run it in my boat the last few year (seafoam), had to replace a fuel pump and a bunch of other stuff. The dealer had a notice on the wall with pictures to stop using it! It works to good cleans and loosen stuff and it jams up pumps and filters. Was better off with some stabil in the tank. by more that one service tech.

So what is going on the Seafoam is breaking off "chunks" and sending them down the fuel line. Or is it taking hard "stuff" and turning it into molasses then sending that down the fuel line plugging up things. Urban Myth is all they are pandering. Last thing they want is a $9 can of Seafoam fixing their $300 plus repair job.The Seafoam didn't create your problems, age and bad fuel did. No way a cleaner can take out a fuel pump. That's just silly.

Not only "silly" it is a flat out lie. ANY competent mechanic will tell you that seafoam will NOT hurt your engine and will do a superior job of cleaning the fuel system. I had more problems with Sta-Bil not doing the job they said it would do as a stabilizer, than the Seafoam ever caused. I run it regularly as a system cleaner and have used it as a stabilizer for up to 16 months, with NO problems.
