Overview

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!

Those funnels work great for me. I have to wonder if the fella complaining ever sumps his aircraft tanks, or understands the principal of water sinking below fuel.

I have used these funnels for quite some time, filtering diesel on the boat and another filtering Avgas for the airplane. For those who complain about fuel being left in the bottom of the funnel after use. That is how it is designed for trapping water. If there is any water in your fuel, that is where it is trapped. Always interesting to pour the residual into a fuel tester and see all the water being collected.

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

I often fuel my plane with 5-gallon cans. I originally ordered the big Mr. Funnel size, but it was too large to have on board with me for cross-country flights. So, I ordered the small size and it works OK. The size of the filter is sufficient in that it does not fall through the fuel port. The filter does not allow a very rapid pour, so if I had to order again, I would probably go with the medium size.

Filter seems to work well. It does leave an oz or two of fuel in the sump. Thats a good thing if you have water or crud in the fuel!
