BALANCE STUB 69-72 24TPI

The 70-6916 is a balance stub used on the inlet manifold of twin-carb Triumph engines, letting the balance pipe tie the two carburetor throats together so both cylinders draw evenly. The catalog lists it as 24 TPI and shows it in service between 1969 and 1972, appearing across several inlet manifold figures including the T120R cylinder block and head listing and the single and twin carburetter manifold figures for the T90, T100S, T100C, T100T, and T100R. The older book form of this part number is E6916, so if you're working from an early parts book that's the number to cross to this one.
