Válvula de presión de la bomba

The B6-02-049 pump pressure valve in the Zenith carburetor of the BMW 600 controls the fuel flow of the accelerator pump and prevents backflow into the pump system. During restorations, it is important to thoroughly inspect used and unrepaired valves and, if necessary, overhaul or replace them, as leaks can lead to acceleration gaps and poor responsiveness. A properly functioning pump pressure valve is crucial for maintaining the engine’s original smooth running characteristics.
