A mechanical fuel injection system retrofit package designed for certain diesel engines replaces the original electronic fuel injection system with a P-series fuel pump. This modification is typically performed on 24-valve engines to achieve increased fuel delivery and simplified tuning capabilities. By substituting the electronic controls with a mechanically governed pump, engine performance characteristics can be altered more directly.
The adoption of this type of conversion frequently stems from a desire to enhance engine power output and achieve greater control over fuel delivery parameters. Furthermore, the simpler mechanical nature of the fuel pump can improve reliability in certain operating conditions and reduce dependence on potentially problematic electronic components. Historically, these conversions gained traction in performance-oriented applications such as truck pulling and drag racing, where precise fuel control is critical.
