    These are the filters made by the Finite division of Parker Hannifin. This is the identical OEM filter sold by Ford dealerships. Ford typically charges $100.00 or more for this exact same filter without the changing instructions, warranty, filter housing o-rings, drain plug, or extra o-rings. The o-rings are made from Buna-N and are the correct durometer (hardness) for CNG applications. I am an authorized Parker Hannifin distributor. I offer discount dealer pricing for box quantities of 10 filters or more. Email me for details.

    VEHICLE COMPATIBILITY

    • 1996 - 2004 Ford Bi-fuel F-150, F-250, F-350 Series trucks
    • 1998 - 2004 Ford Bi-fuel E-150, E-250, E-350, E-550 Series Econoline Vans
    • 1996 - 2004 Ford Bi-fuel Contour

    The recommended filter change interval is every15K miles, or whenever the filter becomes clogged or contaminated. Even if the filter looks clean, there are still particles trapped in the element that reduces the CFM pass through.

    UPDATE
    Parker Hannifin makes two versions of this filter under separate divisions of the company. I now only stock and sell the more robust and superior 050-11-BQ filter from Parker’s Balston division. This is the filter pictured with the o-rings and drain plug that has writing on the side. This decision is based on the feedback I have received from sellers and my own usage after selling and observing over a hundred of these filters. Even though both filters meet the same filtration specifications they do not perform the same. The finite 6T04-023 filter has a tendency to split, dissolves and breaks apart when exposed to the alcohol and PM-5 injector cleaner used to perform fuel line flush. The finite filters have inconsistent wall thicknesses and are more easily crushed during handling. Also, the filter splits in the housing if you over tighten the filter housing (see picture). The Balston filter does not do this. Finally, I am seeing inferior aftermarket versions of the Finite filters that cost substantially less but have the same performance problems.

    I warranty this filter for one year or 15K miles. This way you’re covered until your next filter change. If the filter splits, breaks, or fails I will replace the filter free of charge.

    WHAT IS A COALESCENT FILTER?
    Coalescing filter elements are specially designed to remove liquid contaminants from gaseous flows. Coalesced liquid (water and oil) collects in the bowl awaiting drainage, while clean air or gas exits the housing through the outlet port. Particulate contaminants are captured and held in the media. (See filter housing diagram)

    WHY DOES THIS MATTER?
    Natural gas is gathered from a pipeline and travels to a connecting compressor station. The gas is elevated to pressures ranging from 2000 PSIG up to 5000 PSIG and the resultant CNG is stored in large tanks. The CNG then makes its way to a gas dispenser where it is ready for use in natural gas vehicles. Contaminants can enter into the gas at any stage of this processing. Filters are critical to ensure clean gas as a final product. Contamination that collects during handling, water that condenses in tanks and compressors that leak oil into the fuel stream are all sources of contamination that will shorten the life of expensive equipment, create unnecessary downtime and increase maintenance costs.

    The most common drivability problems I see again and again in natural gas vehicles results from failing to maintain the vehicles coalescent filter. Oil levels in excess of 10 to 80 PPM, parts per million is considered excessive carryover oil. Excessive oil fills the vehicles fuel tanks, reducing the fuel carrying capacity. Oil builds up in the coalescent filter housing, where if not drained regularly, is drawn through the filter into the regulator and into compuvalve (if it’s a Ford bi-fuel) and then into the injectors. The higher temperatures generated by the engine cause the carry over oil to varnish and or solidify. This solidified oil is the most common problem affecting the compuvalve, fuel injector’s catalytic converter. This is a problem unique to CNG vehicles because unlike unleaded gasoline, CNG does not contain detergents.

    The coalescent filter protects your investment and prevents the following problems that are most commonly caused by excessive carry over oil.

    • Damaged Compuvalve
    • Rough Idle, Dying
    • Hesitation
    • Hard Start
    • Plugged Catalytic Converter
    • Loss of Power at Heavy Load
    • DTC Codes For Lean Fuel
    • No Start

    Most dealers recommend changing the filter every 15K miles under normal operating conditions and every 5K – 10K miles under sever operating conditions

    The quality and cleanliness of the CNG at your local refueling station determines whether your vehicle is operating under “normal” or “severe” conditions. Testing the cleanliness of CNG before refueling is unrealistic. There is no way to know if your fuel stations compressors are operating correctly. The best way to prolong the life of your filter and protect your vehicles CNG system from excessive carryover oil is to adopt a coalescent filter inspection and maintenance schedule.

    Some evidence of excessive oil after fueling includes visible oil on the vehicles male fill nozzle. Oil foaming out of the fill hole of the vehicles male fill nozzle. If you see evidence of excessive carry over oil, or if there is more than a teaspoon of oil in your lower filter housing, you should depressurize the CNG fuel system and remove the drain plug to check for oil every 2500 to 5000 miles. I include the extra drain plug o-rings so that the drain plug can be removed multiple times to drain excess oil between filter changes.
