Aviation Fuel Club

Pass the Dream On

A Fuel Club

Sport Aviators make up 80% of all pilots and aircraft. Due to the increase in cost and regulations, Aviation Fuel Club was created to reduce the cost of recreational flying by providing safe, environmentally friendly fuels and facilities. One means of reducing cost is to use commercially available, unleaded high octane fuel for automobiles.

Known as "Mogas" by pilots, more than 50% of all aircraft can use this fuel. However, use of Mogas requires the same quality and handling standards as traditional aviation fuels to insure safety and performance.

Aviation Fuel Club: The Next Chapter

Looking back on nearly three years of hard work, we believe the Aviation Fuel Club’s goal has been accomplished as follows:

  • Reversed the trend in limiting “Mogas” at U.S. airports. Mogas is becoming more acceptable as seen in AFC Director Dean Billing's list and map of airports offering the fuel.
  • Helped re-educate the flying community on the long, positive history of Mogas. Countless articles on the subject have appeared in our newsletters and our GAfuels blog at General Aviation News, many of which have been cited by other media.
  • Assisted numerous airports and pilots with questions related to Mogas safety, costs, insurance, suppliers, STCs, etc.
  • Reported on the dramatic shift in focus among aircraft engine manufacturers who are preparing for a future with Mogas and Jet-A as the two primary aviation fuels.
  • Advised several leading environmental groups opposed to leaded aviation fuel on the potential for its reduction through the increased use of Mogas.
  • Worked with aviation fuel equipment manufacturer (and AFC sponsor) U-Fuel to develop a new line of highly-affordable 'Mini-Fuelers' to lower the cost of adding more fuel options to airports.
  • Assisted several AFC members who have established Mogas distribution companies such as Clear-Gas of Merced, Calif. and AirWorthy Autogas of Phoenix, Arizona.
  • Supported Mogas STC owner Petersen Aviation in educating the flying community on the history of the Mogas certification process that has contributed to Mogas's long history as a safe aviation fuel.
  • Sponsored U2OSH, a symposium celebrating the 30th anniversary of the first Mogas STC at EAA AirVenture 2012.

The Directors of the Aviation Fuel Club are satisfied that our efforts have contributed to real and lasting progress towards our goals. We are grateful for the support of AFC members and our sponsor, U-Fuel, Inc.

You can reach us through our contact links at U-Fuel, on our GAfuels blog and through the Petersen Aviation web site. We will continue to work to lower the cost of flying through more and better options in aviation fuel.

We wish you all safe flying!

Water Guard

Water Guard

Water Guard is a vessel that attaches to the bottom of an aircraft filter or water separator by means of a pipe nipple, to collect water extracted from fuel passing through the filter or water separator.

The Water Guard System contains a float switch, when activated by water, disconnects a low voltage circuit in the Water Guard Explosion Proof Control Box, disconnecting power to the pump and stopping the flow of fuel until the water can be removed by opening a petcock at the bottom of the vessel.

Traditionally aviation water removal systems were only used at large airport fuel farms pumping fuel at high rates intended for use in commercial airlines and large private jets. These water removal systems were large, expensive and could fail if not properly maintained, given the high pressures required to pump fuel at rates over 250 gallons per minute (1,000LPM). In the past, water has been pumped past these filters into aircraft, which has caused accidents.

One option for removing water from fuel is using Water Absorbing Filters that shut off flow of fuel until the filter can be replaced, thereby protecting aircraft. However Water Absorbing Filters also absorb Jet Fuel Additives necessary to protect aircraft at high altitudes, as well as biocides, making them unacceptable.

The only alternative allowing Jet Fuel Additives to pass through a filter is a Water Coalescing Filter or Water Separator. These filters do not stop the flow of fuel in the event of excess water and must be constantly maintained to remove extracted water. This is why ATA 103 requires an Automatic Water Defense System for these filters.

As more small Jet Aircraft are being fueled by Aboveground Fuel Systems, which accumulate water due to condensation, these Systems should include a Water Guard Automatic Water Defense System to detect water and stop fuel flow until the water can be removed.

The Water Guard systems is easily tested by removing the canister from the top assembly, pouring a small amount of water in the canister, reattaching the canister and turning on the pump. The pump will not operate until the water has been removed from the bottom of the Water Guard.

Remote Fuel Islands and Systems

For locations where dispensing must occur at a distance from above or belowground fuel tanks, U-Fuel offers Remote Fuel Islands with dispensers, valves and electrical fittings pre-installed with secondary containment. Transition sumps with underground pipe, valves, fuel monitoring and leak detection systems are available as a package.

Fire Resistant Enclosed Islands

For use in areas where fire codes prevent locating pumps and equipment adjacent to tanks. U-Fuel provides a Fire-Resistant Enclosed Fuel Island with steel hood, fire-rated walls and lockable doors. The fire-rated design allows locating dispensing equipment close to the tank on the same support structure. Options include light with switch, automatic fire suppression system above dispensers, tank and system monitoring equipment, self-service systems and a 20’ tall light pole with LED light that installs at the side of the enclosure.

Non-Enclosed Fuel Islands

For installations not requiring the enclosure and doors, U-Fuel Non-Enclosed Fuel Islands are available with the dispenser and other accessories installed on a steel deck above a secondary containment pan.

Transition Sumps

U-Fuel provides fiberglass sumps for burial adjacent to fuel islands for connecting underground pipe and conduit to the remote tank(s). The liquid proof sumps allow leak monitoring of underground piping.
