This high-pressure fuel pump delivers fuel from the low-pressure system to the injectors at the required pressure for direct injection, ensuring efficient combustion and engine performance.

Function
• Generates high fuel pressure for direct injection systems
•  Ensures precise fuel delivery to injectors
•  Supports optimal combustion and engine efficiency
•  Maintains consistent performance under high load
•  Designed to operate in high-temperature, high-pressure environments

A failing high-pressure fuel pump can lead to poor fuel delivery, reduced engine performance, and starting issues. In high-performance engines like the GT3 and GT3 RS, precise fuel pressure is critical - any inconsistency can significantly impact power output and drivability.

Replacing the pump ensures proper fuel system operation, restores engine efficiency, and protects against potential engine damage caused by incorrect fuel pressure.

When to replace
•   Engine cranks but fails to start
•   Noticeable loss of power or performance
•   Engine misfires or irregular fuel delivery
•   Fault codes related to fuel pressure
•   During fuel system or engine rebuild
