Válvula de presión de la bomba

The B7-03-259 pump pressure valve for the Zenith KL10 and KL11 carburetors in the BMW 700 controls the fuel output of the accelerator pump and prevents gasoline from flowing back. During carburetor overhaul and restoration, this precision component should always be inspected for possible leaks or wear and replaced if necessary to ensure clean throttle response and true-to-original drivability.
