Without the secondary pump, the engine may experience insufficient fuel supply, leading to reduced performance and potential issues. -
Improved Fuel Filtration:
Another critical function of the secondary fuel pump is to aid in fuel filtration. As fuel flows through the system, contaminants such as dirt, debris, and water can find their way into the fuel tank. The secondary pump helps remove these impurities, preventing them from reaching the injectors and causing damage. By ensuring cleaner fuel reaches the engine, the secondary pump contributes to its longevity and reliability. -
Reliable Cold Weather Starting:
In colder climates, starting a diesel engine can be challenging due to thicker fuel viscosity. The secondary fuel pump assists in overcoming this issue by providing an extra push to overcome the resistance caused by cold temperatures. With its help, the engine can start more easily and quickly even in chilly conditions, reducing strain on the battery and starter motor. -
Optimal Performance at High Altitudes:
For those who frequently drive at high altitudes where oxygen levels are lower, the secondary fuel pump proves invaluable. It compensates for reduced air density by supplying additional fuel, ensuring the engine operates at its peak performance despite thin air. This feature makes the 7.3 Powerstroke a reliable choice for individuals living or working in mountainous regions.
