They supply thousands of parts for all kinds of SU carbs and fuel pumps. Their catalog has detailed illustrations and a section devoted to carburetor and fue pump servicing. (Much more informative than the Haynes SU manual IMHO.) The reference ended up costing about $15 with overseas shipping etc. - Curt Onstott
BFS have the current manufacturing rights for the "classic" British carburetters - both SU and Zenith-Stromberg. They can supply parts, complete new carbs, manifolds, and service. Their SU catalog is a wonder to behold, but not entirely enough to do full service. You'll want the Haynes manuals and more, to do that. - Chris Kantarjiev
