In 1905 Mr. George H. Skinner took out a patent for a carburetter in which both the air and fuel passages varied in accordance with the requirements of the, engine. The original design was a clean and simple layout in marked contrast to the multi-jet fixed choke carburetters and it provided a standard of flexibility and economy of operation hitherto unknown. George Skinner together with brothers John and Carl formed the S.U. Carburetter Company in 1910, setting up business in a small workshop in London. The initials S.U. stand for Skinners Union.

From these beginnings the S.U. Company grew into one of the major manufacturers of car fuel systems and components in Europe, its carburetters being widely used on both touring and competition vehicles. S.U. carburetters are to be found on such widely differing types of vehicles as the British Leyland Mini and 'the Rolls- Royce Silver Shadow.

The scope of the Company was later widened by the introduction of its well-known range of electric fuel pumps. More recently the mechanical fuel pump and the sophisticated Automatic Enrichment Device (A.E.D.) have been added. Today the Company produces over two and a half million carburetters and pumps each year and has embarked on further expansion of its manufacturing and development facilities in order to maintain the unique reputation that S.U. has acquired in the field of carburation equipment and fuel delivery pumps.
