THIS PRODUCT MUST BE INSTALLED BY A CERTIFIED MECHANIC. BE SURE TO READ ALL INSTRUCTIONS BEFORE BEGINNING THE INSTALLATION. DO NOT SMOKE AND DO NOT HAVE ANY OPEN FLAME WHILE PERFORMING HIS OPERATION! FOLLOW THE MANUFACTURER’S GUIDELINES FOR RELIEVING FUEL SYSTEM PRESSURE!

IMPORTANT NOTES: for installations on all engines disconnect the negative battery terminal prior to installation. After installation reconnect the battery lead and drive the vehicle over 50 mph (80kph.) for a minimum of 20 minutes. This procedure will reset the computer's memory on, EFI engines, to sense the treated fuel. For diesel and all other gasoline engines, disconnecting the battery is good safety practice.

FITTINGS AND SEALANT: For all models use fittings appropriate to match the fuel system on the engine. Plastic fuel lines require compression fittings with internal reinforcements. Ensure you are using high-pressure hose when required. Use a liquid thread sealant with Teflon or equivalent, which is impervious to gasoline and other fuels. Do not use tape as it could break off and enter the fuel system. The Fitch units are equipped with the following thread sizes and adapters, other sizes are available, contact your local tube fittings supplier.

F50, F100, F200, F300 : UNF straight thread, 9/16-18. O.R.B. tube adaptor to a #6 JIC 37 degree flare.

F400, F500, F750, F1000 : UNF straight thread, 7/8-14. Male O.R.B. tube adaptors to a #10 JIC 37 degree flare

LOCATION:The proper location of the Fitch Fuel Catalyst unit is vital to its efficient operation. It is desirable to locate the unit as close as possible to the injector pump or carburetor and after the filter where possible. Be certain that the location selected has sufficient clearance and that the fuel lines will be free from obstruction and abrasion. Do not mount the unit closer than eight (8) inches (200mm) to any electrical device such as alternators, generators, or pumps as the electromagnetic field they produce can disrupt the efficient functioning of the Fitch® unit. Do not mount the unit closer than eight (8) inches (200mm) to any heat source such as exhaust pipes or exhaust manifolds, catalytic converters or mufflers. NOTE THE DIRECTION OF THE FUEL FLOW INDICATOR ARROW ON THE UNIT. ALL UNITS MUST BE MOUNTED VERTICALLY WITH FUEL GOING IN THE BOTTOM.

This will allow trapped air to escape and prevent air lock as well ensure all the catalyst surface is in constant contact with fuel. The Fitch unit should be mounted in the fuel supply line, not the return line, on the low-pressure suction side of the fuel pump in diesel applications. In gasoline applications the unit can be fitted before or after the fuel pump as in many cases the fuel pump is in the tank. All Fitch units are pressure tested and Coast Guard accepted to 600 PSI.

CONNECTION:If existing fuel lines are too short, additional fuel lines may be added to connect the unit in its selected location. Be sure to use only approved fuel line materials.Caution engines with fuel injection must use EFI rated hose only. Carefully apply the sealant to the fittings at each end of the Fitch unit. Install the fittings to each end of the Fitch unit and tighten. For diesel and fuel injected systems, fill the canister with fuel after installing the inlet line, this will prevent air from entering the system. Use the mounting clamps provided or suitable alternatives; secure the unit in the selected location. Ensure that the clamps are tightened. Check all fuel connections and when satisfied start the engine and let run for several minutes while checking carefully for any leaks.

BREAK-IN PERIOD: The length of this break-in period depends on the age and condition of the engine. An engine in average condition should take approximately 500 miles, (800 kilometers) or 20 operating hours to achieve maximum benefit from the catalyst. During the break-in period the Fitch unit will be cleaning any excess carbon and resins from the engine and fuel system. It is therefore possible to have higher emissions and/or fuel consumption during this period. The cleaning out of this build up from the engine will initially result in dirtier engine oil then normal since much of the carbon residue cleaned from the combustion chamber ends up in the engine oil pan. After the first oil change however, the engine oil will continue to be much cleaner than before use of the Fitch Fuel Catalyst due to the reduction of oil soot contamination.

SPECIAL NOTE FOR LEADED TO UNLEADED CONVERSIONS: It is recommended that at least 500 miles, (800 kilometers) or 10 hours be run on leaded fuel with the Fitch installed before converting to unleaded fuel.

SPECIAL NOTE FOR CARBURETED ENGINES: For maximum performance of the Fitch this engine type should be adjusted after 2000 miles, (3400 kilometers).CAUTIONS: Before installation of the Fitch unit the vehicle should be checked to ensure that it is in good running condition, as it will not compensate for existing electrical or mechanical defects. Do not change from one grade of fuel to another if you wish to evaluate before and after mileage and emissions performance. After the break in period, it is acceptable to evaluate your vehicle with lower octane fuel.Many users experience additional savings with no loss in performance.

Reminder: If the oxygen sensor in engines with electronic fuel management systems is coated with carbon, results with the use of the Fitch may be limited. If this is the case the oxygen sensor should be checked and either cleaned or replaced.

The Fitch Fuel Catalyst will need to be replaced after 250,000 miles (400,000 kilometers), 5,000 hours or whichever comes first.The Fitch Fuel Catalyst is recyclable and should be returned to your local distributor upon replacement. Do not dispose of it in the garbage.

The Fitch Fuel Catalyst has a ninety (90) day money back guarantee provided the installation instructions were followed and the return of the product is based either on product defect or dissatisfaction with the performance.
The Fitch Fuel Catalyst device is guaranteed to be free from defects in material and workmanship for a period of 250,000 miles (400,000 kilometers) (defined by EPA in 40 CFR 85.117), or 5,000 hours from the date of installation. Manufacturer reserves the right to repair or replace any failed or defective device. This warranty does not cover damages resulting from collision, abuse, and improper installation. Return the defective device along with dated proof of purchase to the distributor from which the device was purchased so that the distributor may handle your warranty claim in an expeditious manner. The manufacturer warrants that the installation of the Fitch Fuel Catalyst on a vehicle will not cause the emissions noncompliance of the engine on which it is installed for the life of the catalyst from the date of installation.
