Triumph TR6 North American Model Fuel System
North American Specification Cars
Due to the increasing concern over public welfare with regard to traffic, extensive lobbying with regard to the environment and sheer concern over safety, American legislation has often led the world in attempting to improve all aspects of motoring use. For these reasons, there are a number of aspects about the TR range which are peculiar to North America alone. While many of these local differences are catered for elsewhere on our website, some components have a special relevance and have been included or highlighted here for the benefit of our North American customers.
The original brief for this project was to create the definitive European specification website catalogue for TR6 models and highlight the major components that were different in a separate North American model section. However as time went on and where it was deemed significant to include in the main catalogue sections (the lamp, chassis, body, trim and paint sections are fully world specification) but where it would have required a new section (as in the case of carburettors and emission controls) or where room did not allow it was decided to include significant items on this page as a reference.
Please use the information on this page in conjunction with the main body of the website catalogue and if you require something for your North American model that has made its way into Europe that we don't list, please contact us.
While trying to keep up with the U.S. market emission requirements Triumph used three types of Zenith Stromberg carburetters during the 1970 to 1972 models years. The chassis number change points sometimes ran concurrently. The best method of determining which one is on your car is to refer to the brass tag secured by the top cover screw on the top of each carburetter or by referring to the identification chart.
The carburetters listed are suitable replacements for all models.
