Abstract - Fuel pump is the heart of the engine. It is the
most vital parts of the engine. PT pump means a pressure time fuel pump. When working, PT fuel pump is responsible for oil regulator, PT injector completes the tasks that generate high pressure and timing injection. The most important role is played by the actuator in the functioning of the fuel pump. It is an electronic device which converts the timing of fuel in the system. To remove this actuator, a fixture is needed to be designed and manufacture. This fixture should be designed in such a way that it should be easy to remove the actuator or fuel pump. Safety considerations and also need to taken into consideration. The material used should be softer than that of the material of actuator so that the actuator does not get any scratches. Key Words: Fuel pump, Actuator, O-ring, Fixture. 1. INTRODUCTION Fuel pump is the heart of the engine. It is the most vital parts of the engine. A fuel pump is a component is used in a car or other internal combustion engine device. PT pump means a pressure time fuel pump. PT fuel system is widely used in the upward 10L Cummins diesel engine. Similarly actuator is the heart of the fuel pump. The actuator is used of timing the fuel supply from the pump. This is also a delicate and expensive part which has to be handled carefully.

In any industry, while designing any machine or tool human safety is the first priority. Human safety is most critical element of an industry. Therefore while designing a fixture safety consideration is necessary.
When there is any problem in the fuel pump while testing, the actuator is needed to be removed. Removing this actuator is a difficult task. It is difficult to remove the actuator because of the O-ring. The O-ring is acts as a seal and it gets compressed between two components thus making it difficult to remove the actuator. The previous method of removing the actuator was by using a mallet/screw driver/other tools. This method created a risk of hand injury. Also it was noticed that the actuator was damaged while removing it. Thus to avoid this problem there was a need to design a fixture or a tool to remove the actuator safely and without any damage and hand injury.
Fixture is a device used to hold the work piece or support the work piece. Fixtures are also used for locating a device and it also ensure that the production quality while working in the fixture remains the same. Also it reduces the requirement of skilled labor in the industry. Fixture helps in reducing the cost of manufacturing of any component or work piece.
