Mr. Funnel Heavy Duty Fuel Filters The fuel filter funnel by Mr Funnel is heavy duty, portable, light-weight, self cleaning with fast flowing built -in filter technology that requires no replacement parts. The funnel itself is carbon injected (black model only) when it's made, so it doesn't require a earth mechanism while in use. When fuel is poured through the fuel filter funnel, water and debris will not pass through the vertical standing fluoropolymer-coated stainless steel mesh filter. Only filtered fuel flows through to your engine improving its efficiency and durability and ensuring its proper operation. The sump area in the bottom of each funnel product collects the deflected water and debris to positively reassuring you that you are not receiving contaminated fuels causing damage like what's shown in these pictures above. The fuel filter funnel will filter all kind of hydrocarbons such as petrol, diesel, heating oil, kerosene and 2-stroke mixed fuels
