We were unable to locate an Executive Order number for the Fitch Fuel Catalyst. Fuel upgrade components must be sold legally in California and posses an EO number. EO stands for Executive Order. This is the number given to the product by the California Air Resources Board certifying that it is emissions legal. You will have to present this number to the smog station where your vehicle is being smog checked in order for your vehicle to pass the visual inspection portion of the smog check.
Here is a Link to the California Air Resources Board's Aftermarket Emissions Parts Lookup tool.
