Mr. Funnel, tips on how to properly use the Mr. Funnel funnel to prevent water in your aircraft fuel system.
On July 23, 1996, at 1430 eastern daylight time, a Corben Baby Ace C-1
ultralight aircraft, N75H, lost engine power shortly after takeoff at
Greater Portsmouth Regional Airport, in Portsmouth, Ohio.
The ultralight aircraft sustained substantial damage during the forced landing. The pilot, the sole occupant, received minor injuries. Visual meteorological conditions prevailed and a flight plan was not filed. The local flight was conducted under 14 CFR Part 91. The flight originated at Portsmouth, Ohio, at approximately 1428.
The pilot reported that he had just purchased the ultralight aircraft, and a new engine had been installed. He stated that the engine "...had trouble cutting out..." so he had a mechanic examine the carburetor. He stated that "...it seemed to run OK." The pilot reported that he intended to taxi the ultralight aircraft to accumulate engine time. He stated, "I didn't really mean to take it up...[but a] gust of wind..." caught the wing and the ultralight aircraft lifted off.
He stated that he decided to go around the traffic pattern, but as the ultralight aircraft approached the airport boundary, the engine sputtered, then lost power. The pilot stated that during the subsequent forced landing the landing gear and propeller struck an embankment.
The ultralight aircraft was examined by a Federal Aviation Administration (FAA) Inspector after the accident. The FAA Inspector stated that when he examined the fuel tank, he observed sludge and water in the lower portion of the tank. The FAA Inspector reported that it was not possible to drain the fuel out of the fuel drain due to a clogged fuel drain. Further post accident examination revealed no evidence of pre impact mechanical malfunction.
Your satisfaction Mr. Funnel by
Smart Tech will depend upon how well you understand its design
and proper use. The following Mr. Funnel TIPS
will help you to best use this cost-effective fuel management tool.
1. Carbon powder is injected into the Mr. Funnel plastic so that Mr. Funnel will conduct static electricity (not applicable to colored F1Cs). Grounding is an important safety feature. Always ground Mr. Funnel by Smart Tech.
2. When properly used, the filter will separate FREE WATER from hydrocarbon fuels. Free Water is the collection of H2O molecules in the bottom of gas cans or drums formed when fuel is stored for even short periods of time. The free water formation is due to condensation in the air and/or the separation of water molecules from fuel. Water may be present in hydrocarbon fuels as Free Water or as an emulsion-- small globules of water suspended in the fuel. Water may be emulsified in fuel by vibration or by emulsifying agents such as HEET, alcohol, or detergents. The filter will not remove water emulsified in fuel. We recommend that you filter out Free Water first by using Mr. Funnel, then add such agents to your tank to emulsify any water that may have formed in the tank previously. If both water and hydrocarbon fuels are present in a container and the container is vibrated by shaking or by being transported in a vehicle (including an airplane), water may be temporarily emulsified into the fuel.
Water emulsified in this manner will usually combine and settle out as Free Water in about five minutes after all vibration has ceased. When properly used, the filter will separate this Free Water along with rust and crud from your fuel.
3. Excessive head pressure can force water through the funnel. If most of the filter is covered with water, the head pressure of a full funnel can force water through the filter. As water is observed collecting in the bottom of the funnel or the flow rate begins to slow, stop fueling and dump the water/crud out of the funnel and then continue. (See recommended test in number 9 below.)
4. 2-cycle oil contains dispersants, (detergents) which may allow some water to pass the screen. The only safe way to filter out water is add the two cycle oil to the tank after filtering the fuel through the funnel.
5. Dry gas (HEAT and alcohol) can emulsify and bind water. See # 2. The filter cannot remove this bound water. Filter fuels before adding dry gas. The filter will stop water from going into your tank; the dry gas will absorb moisture already present in your tank.
6. DO NOT ATTEMPT TO REMOVE the filter from. The filter is permanently attached to the funnel. (It wouldn't work "in line" anyway due to increased head pressure, so don't try it!)
7. Mr. Funnel is designed to work with gasoline, diesel, and kerosene. CAUTION: Do not use Mr. Funnel for anything else. Other products can compromise the effectiveness of the filter.
8. CAUTION AVIATION USERS: For aviation use, the purpose of
this product is to facilitate the inspection of fuel for contamination in
the form of solids (down to .005 inch) and free water.
9. Always test Mr. Funnel before its first use. There's a 30-day unconditional money-back guarantee. Pour a cup of water into the F1C and F3C or 2 cups into the F8C. This amount of water should not pass through the filter. (Of course, we know that you'll probably pour water into the funnel until it leaks. Keep this amount in mind when using Mr. Funnel, knowing that the head pressure caused by the weight of this amount of water in the funnel will cause water to pass through the Teflon coated stainless steel screen.)
10. Frequently inspect the funnel for physical damage. The filter is stainless steel coated with Teflon. With proper us your Mr. Funnel should last for a long, long time.
Teflon Coated Stainless steel Filter Separates
water and Dirt from Gasoline, Diesel
Kerosene. Manufactured out of industrial Standard Electro-conductive Polypropylene and can be grounded for extra safety. Fast Flow fuel Rate. Filter Material is the same used to protect the U.S Army M-60 and M-1 Combat Tanks.
Self Cleaning with no replacement parts.
