A Fuel Pump Plunger Spring acts as a return mechanism for the plunger within the fuel pump. It is made from durable material such as bronze and helps to provide a high spring force in a small space, allowing for efficient load distribution and absorption of shock and vibration.Attributes:• Applies a uniform pressure over the surface area of the other components that come in contact• Helps to compensate for this wear by maintaining the proper tension and alignment between the components Applications:A Fuel Pump Plunger Spring helps to maintain proper tension and preload on the plunger fitted within the fuel pump assembly and provides flexibility by allowing for proper alignment of components.
