The primary function of the prime pump located in the rear of the Joint Light Tactical Vehicle is to prime the fuel system. This mechanism is essential for ensuring that the fuel system operates effectively, especially during initial startup when the fuel system may be empty or if it has been evacuated due to maintenance or other reasons.

Priming the fuel system helps to eliminate air pockets that can hinder fuel delivery to the engine, promoting efficient engine performance and reliability. By facilitating the flow of fuel, the prime pump ensures that the engine receives a steady and consistent supply, which is crucial for both starting the vehicle and operating it under various conditions.

In contrast, draining fuel pertains to maintenance tasks rather than operation, cooling the engine involves a separate system dedicated to managing engine temperature, and filtering air is a function of the air intake system, not the fuel system. This distinction clarifies the essential role the prime pump plays in vehicle operation.
