In-Tank Fuel Stabilizer Filter (2-Pack)

What's in the Package: The FUEL LIFE comes with two stabilizing filters, two tags, two clips, and two tether lines. How it Works: You have three options to install. 1) drop the filter into the fuel tank, 2) attach a tether line to the filter on one end and a tag on the other, then drop the filter into the tank and leave the tag outside the tank while you screw on the cap, 3) attach the line to a clip which can then be attached to whatever keeps your fuel cap in place. I don't see anything preventing you from combining options 2 & 3 and using both the tag and clip. In fact, I'd recommend that as being extra secure and the tag has a place to note when you installed it. I think this system is too complicated. First of all, I'm not that excited about dropping the filter inside my fuel tank. I bought this to use with my lawn mower and roto tiller, and it turns out the filter is so big you kind of have to smash it into the tank to get it to fit. (both my machines are walk-behind models). I think the filters are too large to work something you would carry like a string trimmer or chain saw. So, I attached the line and a tag to be sure I could get it out. The line is very fine, not much thicker than a human hair, and is kind of hard to work with. It took a few minutes to tease it out into a long strand, and then you have to tie knots in it. I dropped it once and had to get a flashlight to find it in my carpet. Positives: it's a two-pack, so you could protect two engines for 2 years. It works "for all fuels and fuel blends: gasoline (ethanol & ethanol free). About the only application where I think this may be a superior product to an additive would be something like a generator where you aren't using it very often and want to keep fuel in the engine. I think for something used regularly during a season, like a lawn mower or snowmobile, you'll be refilling the tank often enough that you're better off just protecting your stored fuel.

I have several gasoline powered small engines that only run once or twice a year so you have to add the liquid fuel stabilizer every time you finish with it or you have to empty the fuel from the bowl so it will start next time you need it. The fuel Life stabilizer filter pack will last two years in the tank so you dont have to dope the fuel after every use or drain the tank. The individual filters just drop in the tank and the have a small string attached so you can attach a tag with a date so you know when they expire. The pack comes with everything you will need.

Okay, this has to be one of the most difficult items to write a review. I have all intentions of using one in each of my riding mowers because I've noticed a lot of hesitation in both that I suspect is from different contaminants in the fuel after it's sitting idle for so long. Unfortunately, I cannot open the package because it states to insert in a five gallon tank within 15 minutes of opening. I live in an unseasonably weatherized area and am unable to check the functionality of the product because there's still snow. I'm hoping in a couple weeks, I can use this product and fingers crossed it cures the issue. I have high hopes.

The manufacturer of FUEL LIFE makes it difficult to find out exactly what is in it and how it is supposed to work. There are two patents referenced. The first, 9,149,788, is clearly irrelevant as it describes the use of activated charcoal as a stabilizing agent, and at least this version of FUEL LIFE has none. The second patent, 8,828,104, is more interesting and appears to describe the construction. Inside a porous nylon sleeve are pellets of zeolite (a clay-like substance), and at least according to the patent, a gelling agent. Unless the gelling agent is somehow incorporated with the zeolite, I saw no evidence of such an agent. One of the photos I have attached shows the reddish-brown zeolite pellets inside the sleeve. I tested moisture absorbency by placing one of the FUEL LIFE devices in a sealed container along with a hygrometer (measures humidity). If the device did absorb moisture, the humidity level should drop and indeed it did, from 42% to 25% over the course of a day. It stabilized at 25% after that - I note that with silica gel desiccant, I can get the reading down to 10% (the lowest it goes on this cheap meter.) In the package are two of the FUEL LIFE devices, two plastic tags and two lengths of nylon cord. The idea is that you use knots to attach a tag to one end and a device to the other. You then drop the device in the fuel tank and have the tag exposed to let you know it's there and to retrieve it when desired. I can believe that this will absorb a small amount of water from the fuel and that can help. But long-term storage of gas has other issues, such as gum being formed, and I don't think FUEL LIFE can help with this. I would not choose to purchase this as sole protection for gas in outdoor power equipment, and have had good luck with more traditional fuel stabilizers.

FUEL LIFE In-Tank Fuel Stabilizer Filter (2-Pack), what a good idea. I've been using fuel stabilizers for years. The tough part is to have some fresh stuff on hand every time you fill the tank. Not any more, if it's already in the tank. Comes with a little cord that let's it dangle in the tank for the 2 years that it lasts. It has a tag you can mount anywhere so you will remember to change it out also. The most difficult part of the whole deal was getting my old fingers to tie the tiny cord. What a good idea.

These Fuel Life In-Tank Fuel Stabilizers Filters come in a convenient two pack that and greatly increase the life of stored fuel in tanks and storage containers. These easy-to-use pouches drop right into the fuel tank and have an attached string which can be used to anchor it to the lid or rim of tank. This sack continues to remove impurities and push moisture out of the fuel area and out of your engine. This will make startup after high humidity times or after long periods of storage. Providing treatment for up to two years these FUEL LIFE In-Tank Fuel Stabilizer Filter are a must have for those ICE lawn care motors.

This is a simple solution to treat gasoline in all of your power equipment in the garage. It is easy to use. You just attach the string to the stabilizer absorbent pad drop it in the tank and that is it. The directions says it last for up to two years but I would probably replace sooner out of precaution since there is no way to tell the products end of life usage.

Great concept: fingers crossed. Living on a farm, I count on certain gas engines to perform when needed. Case in point is our side-by-side mule. The mule sits outside in the elements and is used almost daily. Still, moisture buildup is always a concern. The Fuel Life Fuel Stabilizer concept sounds perfect for my situation. I normally add a stabilizer to the storage tank but not in the individual tanks, so the idea of something to reduce moisture in a gas tank sounds perfect. It may last two years, but I’ll know sooner than that if it works. If it works, then I plan to purchase several of these for gas engines.

Really hoping this works ! Love the idea of not having to drain your tanks for storage of lawn mowers , snow plows, generators when not in use for the off seasons.It says they will last up to two years but I think that would be pushing it. I would for a year but that's not necessary in most cases. I like that you can just drop it in the tank and tether it to the gas cap, and the small tab you can write the date you placed will help to remind when to change. Genius !

I have not always used gas stabilizers - but I forget to add them until it's been too long - so the 2-year life of the Fuel Life In-Tank Fuel Stabilizer Filter (it's a 2-pack) caught my attention. It's a permeable tube-like filter containing a granular ingredient you simply add to your fuel tank (with a tether so you can retrieve it 2-years later). I found it real easy to use; just tether it and drop it in the tank! On my Side-by-Side I needed to protect the spare gas can (2-gallons) and the main tank (9-gallons). There is a 5-gallon limit per filter. My solution was to go for a fun ride and get the gas in the SxS tank down to half a tank!
