As a factory-sourced component, this nut is manufactured to the exact specifications required by the Isuzu 4LE2 engine's fuel feed pump assembly.

Key Features

• OEM-Grade Thread Integrity — Manufactured to exact dimensional tolerances for the 4LE2 engine's fuel feed pump, ensuring secure fastening without risk of cross-threading or fuel system leaks.
• Direct OEM Replacement — Installs in place of the original hardware with no modification to the feed pump mounting interface on DCA25USI units.
• Confirmed Fitment for DCA25USI — Specifically validated for the DCA25USI ultra-silent generator powered by the Isuzu 4LE2 diesel engine.
• Fuel System Security — A correctly torqued feed pump nut maintains a sealed, stable fuel circuit, supporting consistent fuel delivery and uninterrupted generator output.
• Fuel System Safety — A properly secured feed pump fastener is critical to preventing fuel leaks within the generator enclosure, reducing fire and contamination risk during operation.

The feed pump nut secures the fuel feed pump to the engine block on the Isuzu 4LE2 diesel engine, maintaining the alignment and seating of the pump within the fuel delivery circuit. A correctly fastened nut ensures the pump draws fuel consistently from the tank and delivers it at the right pressure to support stable combustion. If this nut loosens, strips, or fails, the feed pump can shift or lose its seal, leading to fuel starvation, erratic generator output, or fuel leakage within the enclosure.
