These rubber intake manifold adapters will adapt a wide variety of carburetors to their manifolds.  We use them for some of our Triumph and Norton carburetor kits.  Made from high quality hose that resists heat and UV cracking.  The rubber adapters also help to insulate the carburetors from engine heat.  Adapter kit includes two rubber carburetor holders that measure 38mm (1 1/2") ID x 48mm (1 7/8") OD x 44mm (1 3/4") length and four hose clamps.
