Multiquip 8943672941 Fuel Filter Sensor Assembly DCA25USI 4LE2

The Multiquip 8943672941 Fuel Filter Sensor Assembly DCA25USI 4LE2 is a genuine OEM component designed for the DCA25USI ultra-silent diesel generator. As a direct OEM replacement, this assembly is sourced to the exact specifications required by the Isuzu 4LE2 engine used in DCA25USI units, ensuring correct sensor output and filter housing compatibility. If you are servicing a DCA25USI generator, this is the authorized part to restore the fuel system to proper operating condition. DHS Equipment stocks genuine Multiquip OEM parts to keep your equipment running as originally engineered.

Key Features

• Genuine OEM Sensor Accuracy — Built to the exact electrical output specification of the Isuzu 4LE2 fuel system, ensuring the sensor reads fuel conditions correctly and communicates accurate data to the engine management system.
• Direct Assembly Replacement — Supplied as a complete sensor and filter assembly, allowing straightforward installation into the DCA25USI fuel circuit without sourcing individual components separately.
• Confirmed Fitment for DCA25USI — Engineered specifically for the DCA25USI ultra-silent diesel generator equipped with the Isuzu 4LE2 engine; check your model plate before ordering to confirm compatibility.
• Fuel System Integrity — A functioning fuel filter sensor assembly maintains clean, uninterrupted fuel delivery to the 4LE2 engine; a failed or degraded unit can trigger false fault codes, cause unplanned shutdowns, or allow contaminated fuel to reach injectors.
• Fuel System Safety — On a generator running in critical or continuous-duty applications, a correctly operating fuel sensor is essential for accurate fault detection and controlled engine shutdown, protecting the unit from fuel starvation damage.

The fuel filter sensor assembly performs two functions in a single unit: it filters particulates and contaminants out of the diesel fuel supply before they reach the injectors, and it monitors fuel condition or flow to provide feedback to the engine control system. On the DCA25USI with its Isuzu 4LE2 engine, this assembly sits within the fuel delivery circuit and is a critical checkpoint between the tank and the engine. When the sensor portion fails, the generator may log fault codes, enter protective shutdown, or run erratically even when the fuel supply itself is clean. When the filter element degrades, restricted flow or contamination can cause hard starting, rough running, and accelerated injector wear.
