Compatibility
This plunger is a service part for Zexel (formerly Diesel Kiki) fuel injection nozzles bearing the model codes A724, A741, A769, and A156. These nozzles are commonly found in a wide range of mid-to-large displacement diesel engines from Japanese and global manufacturers, including but not limited to Hino, Isuzu, and Mitsubishi Fuso trucks and industrial power units. Compatibility is determined by the injector nozzle model, not the vehicle model.

FAQ
Q: How do I confirm this plunger is the correct part for my injector?
A: You must identify the model code stamped on the body of your Zexel injector nozzle (e.g., A724, A741). Match this code to the compatibility list. The plunger part number 090150-4810 corresponds to these specific nozzle models.
Q: Can this plunger be installed as a single component in a worn injector?
A> For optimal performance and longevity, it is highly recommended to replace the plunger and its matching barrel as a matched set. Installing a new plunger into a worn barrel can lead to rapid wear and poor fuel control. Professional injector rebuild kits often include both.
Q: What are the symptoms of a worn injector plunger?
A: Common signs include hard starting, rough idle, loss of engine power, excessive black or white smoke, and increased fuel consumption. These issues arise from compromised fuel pressure and inaccurate metering due to plunger wear or scoring.
