The Fast Flow fuel taps have a high flow rate and ensure a perfect supply of fuel to the carburettor even on powerful engines. They can be replaced 1:1 with the original fuel tap. The version shown here is a special version for wideframe with the fuel outlet in driving direction to the right.
The functionality corresponds to that of a conventional fuel tap (open/reserve/close). Here, when the reserve level is reached, the fuel tap is manually switched to reserve. Nice feature on the side: The reserve level is about 1 liter larger than the original fuel tap.
