Petcock Adaptor 1/8-3/8 BPT BSP thread Triumph Norton BSA Everything Else-1 to my knowledgeMost likely used with BSA and their large fuel tank petcock threads, but such threads came on other models as well. If in doubt, the hole in your tank is roughly 5 8" SAE. Such an adaptor allows use of still available (sometimes cheap) 1 8 British Standard Pipe petcocks. Includes fuel filter shown. Sealing washers or teflon tape required, not supplied.
