General information about this item

Product info
The ball valve with part number B7-03-063 functions as a self-acting check valve in the diaphragm pump of the BMW 700 and ensures a secure seal for the fuel flow. As part of a restoration, it replaces worn or leaky original valves, thereby preventing pressure loss and backflow into the tank. This reliably restores the original operational reliability of the fuel system.
