FITTING INSTRUCTIONS

FITTING INSTRUCTIONS - IN-TANK GAUZE

(For in-Line Units refer to Warranty Card)

INTRODUCTION. To be fully effective it is important that a) the engine is in a good state of tune and b) that the Catalyst Gauze is fitted to rest at the bottom of the fuel tank. Care must be taken to ensure that the Gauze is at the lowest level; this is particularly important for tanks that may have internal baffles or are foam filled (this is very rare). The Gauze itself is 5 inches long and 1 inch in diameter (a large sausage size). It is not flexible and will not go round a sharp bend in a filler pipe, for example.

ECONOMY. The Broquet Catalyst will provide more available engine power and provided this extra power is not used entirely for greater speed then mpg will improve after the catalyst is fitted (even with lower octane unleaded petrol). To measure this improvement it is important to determine the present mpg figures prior to fitting so that subsequent economy benefits can be measured.

SWITCHING TO UNLEADED. For petrol engines currently using 4-Star leaded we suggest a gradual introduction to unleaded over a few fill-ups. The 500 mile "run-in" period on leaded mentioned in the Warranty Card is not strictly necessary. We do not recommend use of Lead Replacement Gasoline which is not subject to any British Standard and which has caused all sorts of problems in Sweden since its introduction in 1991.

FITTING. Depending on fuel tank and filler pipe layout the options for fitting are as follows:

  1. Sliding the unit directly down the fuel filler pipe (not for cars fitted with catalytic converters as the pipe will be too narrow) after ensuring that there are no bends or other obstructions such as an anti-syphon device. If you are unsure how straight the pipe is try first with a suitable length of not too flexible hosepipe. Please feel free to "turn in" the rather sharp "fin" ends of the gauze mesh as this may help prevent the unit from catching. NOTE. THE UNIT MUST NOT GET STUCK IN THE FILLER PIPE AS IT WILL NOT WORK IN THE PIPE AS IT NEEDS TO BE IMMERSED IN THE MAIN BODY OF FUEL IN THE TANK ITSELF.

  2. Removing the gaiter/coupling at the junction of the tank and the bottom of the filler pipe and placing the Gauze directly in the tank. Many vehicles have this type of coupling which is often readily found by removing the rear wheel on filler side. Make sure the tank is fairly empty to avoid spillage.

  3. Removing the fuel level indicator (sender unit) and dropping the unit directly into the tank. The sender unit is usually on the top or the side of the tank sometimes accessed via an access plate/inspection panel under the carpet in the boot or rear floor panel or under the back seat.

If it is required to retrieve the Gauze at a later date then a steel or nylon "wire" (fishing line or similar) may be attached to the Gauze and routed to an external fixing point. It should be noted however that the cost of the Gauze is likely to be more than recovered when a vehicle is disposed of as a "converted" vehicle which almost certainly meets MOT regulations on exhaust gas emissions.

IMPORTANT NOTE Extreme care should be taken when working in the presence of fuel tanks due to the presence of highly inflammable fuel vapour. Always use special tools to avoid the possibility of sparks and, if in any doubt at all, seek assistance from your regular garage.

To maintain maximum benefit from the Catalyst we recommend that the CO level should be set at the optimum level recommended by the manufacturer at the next service.
