Fuel tap by Olympia for Vespa PX Arcobaleno 80/125/200.
The fuel tap is supplied including rubber gasket, nut, choke lever, and retaining pin.
A well-closing fuel tap relieves the float needle valve. When cleaning the carburetor, the ability of a reliably closing fuel tap is also of considerable advantage. The fuel tap also has a built-in pre-filter, which prevents larger impurities from entering the carburetor.
