Installation of a diesel pump in a 1HZ engine

Installing a diesel pump in a Toyota 1HZ engine is a detailed process that involves several steps. Here's a general overview of the procedure:
1. **Remove the old pump**: Begin by disconnecting the fuel lines and removing the old diesel pump from the engine.
2. **Align the new pump**: Place the new pump in position and align it with the timing marks on both the engine and the pump.
3. **Tighten the bolts**: Secure the new pump by tightening the bolts to the manufacturer's specified torque.
4. **Connect the fuel lines**: Reattach the fuel lines to the new pump, ensuring they are properly fitted and secure.
5. **Test the engine**: Finally, start the engine to ensure that the pump is working correctly and the engine is running smoothly.
Remember, working with fuel systems can be dangerous, so take all necessary safety precautions, such as working in a well-ventilated area and keeping fire extinguishers handy.
