A carburettor inlet adapter with an AN6 37-degree flare and a 7/8*20 thread, in the shorter 30.8mm body length. The 7/8-20 inlet is the fuel entry thread used on many performance four-barrel carburettors and dual-feed bowls, and this fitting replaces the original inverted-flare inlet so a -6 AN braided line can be run to the bowl. The shorter body is the one to choose where space around the carburettor is tight, such as under a low bonnet, beneath an air cleaner base or where a linkage or throttle bracket sits close to the inlet. Confirm your carburettor’s actual inlet thread before ordering, as 7/8-20 and 9/16-24 inlets are not interchangeable.
