FloTool F3NC 3.5 GPM Non-Conductive Fuel Filter

Owning a late model mower with a plastic carb that has a very small metering jet means, any tiny speck or fuel oxidation will instantly clog it. It's a real pain to have to stop in the middle of mowing to tear down the carb and clean it out again. This got old quick from a less than brilliant design. I now use this FloTool filter/funnel each time I refill the mower tank. The fine mesh screen works great as a filter and appears to not allow the static pressure of any water/moisture to pass through. This can occur even with EFG which I use exclusively in all of my small engines.. Couldn't be happier with the results. A perfect solution product ! I'll be using it when fueling "all" my power equipment from now on. Only wish I knew about it sooner.

this is the best filter funnel, stops water and trash. Saved a lot of gas.

This filter funnel works well. My use is to filter my parts washer solvent when draining the tank. Yes, there is a small bit of waste, but I don't feel it is significant. I should have ordered the 2/3 filter unit. The opening diameter on this funnel is about 6" and flow rate is around .6gpm. If you are needing more size or flow, get the larger version.

Gives me peace of mind when putting gas in things.

Must have if you own a generator or store fuel for emergencies. Water is gonna get in your gas with storage if you store it outside and even in a shed through condensation. Hurricane Helene taught me alot and the last thing you want is an owning a generator and the only gas available to you have is bad and without a way to get more. This effectively removes all water from gas so the things you depend on work will you need them to.

The filter no doubt will not let water pass but what I don’t get is that it has a pretty deep well below the filter which I guess is supposed to let heavy debris fall in to, but this leaves you with a shot glass of fuel which I guess is supposed to be discarded or collected and saved to refilter after you have enough? This makes using it cumbersome, surprised no one else reviewed on this?

Reading Is Fundamental which many that left a bad review fail to do. after the filtering , the product left in the sump look and smell like gasoline, trust me ( Not gasoline ). If you keep using this product and discard what is left in the sump. For a few days your engine with feel a tad more hot ( trapped water be it in the gas line or tank. The Lifters will quiet down ( that tic tic tic sound from the engine ). More power to the engine. Better voltage charging. Start up faster in cold weather. Better heat during winter months. A typical gasoline mixture contains about 150 different hydrocarbons, including butane, pentane, isopentane and the BTEX compounds (benzene, ethylbenzene, toluene, and xylenes). Gasoline also contains lubricants, anti-rust agents and anti-icing agent. Some gasolines also contain ethanol, which is made from corn. This product filter to almost pure gasoline. Pure gasoline is a solvent that will clean: gas tank from rust. Clean your fuel line as well fuel filter ( many cars have many fuel filters ). Clean your fuel pump. You may not know the arm of your fuel pump the meter to gas volume will rust from ethanol ( indirectly ). molecules in gasoline expand and contract depending on outside temperature. ethanol bond to water even water in the air. Thus the accumulation of moisture in tank. Ethanol in fact not all that much cleaner just make carbons less dense. Lighter carbons move to the upper atmosphere. This why back in the 1800's water in cast iron pots was kept in wood burning fire place when in use. ( less chimney cleaning ). Gasoline with ethanol prone to phase separation ( gasoline break down ie gasoline lack cohesion). They tell you, you can not remove Alcohol, yes you can and my truck run much better for using the product. Thank You a answer to prayers.

Very good and práctical

Using this product to separate dirt and water from diesel fuel I have stored in shed for long time.

Before using this funnel on fuel I decided to fill it half full of water from the tap. I was so amazed that not one drop of water would penetrate the screen. The outlet of the funnel was 100% dry, I even shone a flashlight up there to make sure. After all, diesel must be free of water and the manufacturer's promise holds true. The instructions do state that if you have an emulsifier additive in the fuel, water will go through. Fuel, however, goes through very quickly and comes out clean. I will gladly recommend this product! I have been disappointed more than once over excess contaminants in fuel from gas station pumps.

Recommended for boats. Filter element is about one centimetre up from the bottom (guessing to collect any water in the fuel) but means there is always a little fuel to dispose of some where after every use

Muy buen producto, la verdad filtra solo la gasolina, no deja que pase el agua

Très efficace. J'ai pu récupérer l'essence d'un réservoir dans lequel eau et essence étaient présents.
