Norton Commando petrol tap 033155 — early type main petrol tap, chrome finish, 1/4″ BSP GAS thread.
The 033155 is the early-type main petrol tap for Norton Commando 750 and 850 models, as well as select late Triumph twins and triples using 1/4" BSP tank threads. Chrome-plated brass body with a flat lever, built-in mesh strainer, and internal standpipe pickup — so the main tap draws from the bottom of the tank while leaving fuel available for a separate reserve tap on the opposite bung.
