How to add Sea Foam to a capless fuel tank system

Brian gives a short demo on adding Sea Foam to a newer car and truck with a capless fuel filler neck. Even though capless vehicles include accessory funnels, there are low cost aftermarket options that offer particular advantages, especially when you lose one! Nice to have extras handy, plus they also work great with standard tank types.

I work at a gas station that sells seafoam. Whenever a customer comes and buys seafoam to put in and has this type of gas lid i have to tell them i have no way of getting it in. You guys should just add a funnel attached to the can of seafoam it will make it alot simpler and practical.

I had a 2012 Ford Fusion and began adding SeaForm to the tank...before my fuel mileage was 25.6mpg after using (especially on long trips) I began averaging 30mpgCity and 38.2 mpg hw.... awesome additive!!

It might be easier for the general public if the bottle is redesigned for this purpose.

That’d been nice to know as I poured half the bottle down the side of my truck 😂 Guess I shoulda read the instructions oops

The capless gas fill. They are absolutely terrible. After a recent rain I opened the fuel door and observed water pooled on top of the trap door. I had to blot it out with a dry paper towel trying not to push against the trap door. There is no telling how much water has penetrated the trap door.

I get the bottles into the capless fuel tank then it spills through on to the pavement under the car. What's with that? It seems as if the nozzle isn't long enough, but it doesn't spill from the top. It's coming from somewhere behind the metal door on the fuel tank. Nothing should escape after penitrating the metal door. Is there something wrong in there?

[FonzAllahh]

do you add this before or after getting gas & about how much has should be in the car to add the full bottle?

[its_beautybee]

Should we pour the whole can into the gas tank or just some of it

[tonyayaladm]

agreed i need the dang funnel and just realized

[lisamyers]

Can sea foam help loosen a stuck fuel indicator?

[He_was_number_]

On a 18.5 gallon gas tank that's half empty do I add half the 16oz can or do I add all of it ?

I see you are using it on a flex fuel vehicle. Can Seafoam be used with a tank full of e85 ethanol? I want to start doing treatments for my Grand Caravan, but run exclusively on e85. Thanks!

I have a question. is it okay to add a whole can of sea foam to my gas tank?

[natehobbs]

why would you use seafood in a new truck?

[hibbityhoobla]

Now when adding to gas does it clear and clean Fuel pump assembly, iinjectors and all the lines

[kangaroobooks]

Essentially, what is sea foam, and why would I want to use it..on two year old fiesta?

The new smaller size bottles have a thinner neck to work with capless tanks. Just save the bottle then cut the bottom off and now you have a funnel. If you plan to use the larger bottles in the future

You know you're in America when grown adults can't figure out a simple solution lol. These comments are golden

We shouldn’t have buy a funnel to use this product!
