Diesel Kiki Injection Pump Delivery Valve P10-18

Diesel Kiki/Zexel Delivery Valve Assembly. A small, highly precise metal component consisting of a valve and a seating area (under a plastic cap marked Diesel Kiki). This valve is crucial inside the diesel fuel injection pump; it maintains high fuel pressure and controls the timing and cutoff of the fuel delivered to the injector lines. The cross-and-square mark on the top suggests precision engineering, typical of injector parts.
