I have a couple tees made up. The inlet (middle barb), is 6.35mm (1/4" ) to fit the OEM fuel pump. Outlets are 8mm (5/16") to fit your Kadrons or other carbs with a 5/16" / 8mm inlet. This makes for a clean, one piece install, no extra fittings, no extra opportunities for leaks, less clutter. All brass, compact. $12 USD + shipping.
