Mr. FunnelŪ Fuel Filters are simply amazing. Dirty fuel in.... pure fuel out. It's that easy.

The specially designed filter removes water and dirt from gas, even 2-stroke mixtures. Ethanol attracts water more than regular gasoline. Never before has a fuel filter been more important.

Dirt and water are practically unavoidable in stored fuel, causing microbial growth, corrosive acids, electrolysis and rust. These contaminants can plug filters, corrode components, decrease efficient combustion and cause engine shutdown or system failure.

When fuel is poured through the Fuel Filter Funnel, water and debris will not pass through the filter's fluoropolymer-coated stainless steel filter. Only filtered fuel flows through to your engine, improving its efficiency, durability, and proper operation. The sump area collects the deflected water and debris for proper disposal. The Fuel Filter Funnel will filter gasoline, diesel, heating oil, kerosene and 2-cycle mixed gas.

The Fuel Filter Funnel is a heavy-duty, anti-static, and fast flow funnel with built-in filter technology.

Lawn mowers, tractors weed trimmer/blowers, dirt bikes/ATVs, boats, even airplanes... will have longer useful lives if owners filter their fuel!

Works just as advertised. It takes fuel as fast as I can pour it from a fueling can.

filter works great but does not fully drain contents. Lack of drain funnel on top makes a messy job of returning un-used fuel to your jerry can.

Terrible funnel for several reasons, I discarded it after a single use. 1. The funnel doesnt completely empty - a couple hundred ml remain in the bottom of the funnel, and need to be dealt with after fueling - either thrown away or back into a gas can with another funnel. 2. The flat bottom (unlike a regular tapered funnel) causes gas to splash out all over the wing and yourself while fueling. 3. The flow rate on the large funnel isnt enough to keep up with pouring from a gas can - I had to stop and wait for the funnel to drain several times with each can I poured in.
