Did You Know... Racor Has Filters in a Funnel?
StartSystemHeader EndSystemheader StartFragment
The Racor Filter Funnel (RFF) family is a heavy-duty, fast flowing, filter-in-a-funnel that separates damaging free water and contaminants from gasoline, diesel, heating oil and kerosene.
Racor RFF funnels are capable of removing free water and solids down to 50 micron and allows you to visually inspect the integrity of your fuel supply as you refuel.
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 can cause engine shutdown or system failure. Now there's no reason to blindly put suspect fuel into your tank. With a Racor Fuel Funnel you can filter it as you dispense.
Great for refueling lawn mowers, chain saws, snow machines, ATVs, power generators, boat motors, PWCs, RVs, motorcycles, etc. Racor filter funnels are for people who need clean dry fuel on the go.

How They Work:
The Racor Filter Funnel comes complete with a built-in DuPont Teflon® PTFE (polytetrafluoroethylene) coated stainless steel screen filter. As fuel is being filtered, free water and contaminates collect on the bottom. Because water is heavier than fuel, free water will settle to the bottom. When you have a substantial amount of water (approximately 1 cup), dispose of it properly and resume refueling.
When properly used, the filter will separate free water from hydrocarbon fuels. Free water is the water that collects in the bottom of fuel cans, tanks, or drums; formed when fuel is stored for even short periods of time due to water con-densation on cool tank walls. Water may be present in hydrocarbon fuels as free water or as an emulsion; very small droplets of water suspended in fuel. Water may be emulsified in fuel by a high speed pump, vibration or by emulsifying additives such as alcohol or detergents. The RFF filter will not remove emulsified water. Instead, install a Racor fuel filter/water separator to remove emulsified water from your fuel delivery or engine fuel system.
Excessive filling will cause head pressure and can force water through the funnels filter. If funnel filter is more than 1/3 covered with water and flow rate begins to slow, stop fueling immediately, properly dispose of water and contaminates from the funnel, then continue fueling.
2-cycle oil contains detergents, which may allow some water to pass through the filter screen. The only safe way to filter out water in this case is to add the 2- cycle oil to the tank after filtering the fuel through the funnel. Additives containing alcohol can emulsify and bind water to fuel. The filter cannot remove this bound water. Add additives after fueling.
Do not attempt to remove the filter from the funnel, filter is permanently attached to the funnel.
The RFF is designed to work with fuels only. CAUTION! Do not use the RFF for anything but filtering fuels, other liquids may compromise the effectiveness of the filter.
Another purpose for using a RFF is to facilitate the inspection of fuel for contamination in the form of solids (down to 50 micron) and free water. Don’t forget to check the fuel filter sump for water. If water or contamination are found, dispose of properly.
To test the RFF, simply fill with water, roughly 1/3 the way up the screen. This amount of water should not pass through the Teflon® coated filter screen. Keep this amount in mind when using the RFF knowing that the head pressure caused by the weight of more than this may cause water to pass through the screen.
Always dispose of water, contaminates, or dirty fuel in a proper manner. Periodically inspect the funnel for physical damage. Store the funnel properly as some fuel may remain on the surfaces.
