The Multiquip M3373101203 Air Cleaner Hose is a genuine OEM component designed for DCA125USI3CAN and DCA125USI ultra-silent diesel generators. As an authentic Multiquip OEM part, the M3373101203 is manufactured to the exact dimensions and material specifications of the original, ensuring a correct, trouble-free installation. This hose connects the air cleaner assembly to the intake path, maintaining the sealed airflow routing that these generators depend on for consistent, clean operation.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional spec for this hose routing, ensuring the correct inner diameter, wall thickness, and flexibility for the DCA generator air intake system.
- Direct-Fit Installation — Matches the factory mounting points and connection ends on the air cleaner assembly, slipping into place without trimming or adapter fittings.
- Confirmed Fitment — Verified for DCA125USI3CAN and DCA125USI ultra-silent diesel generator models.
- Airtight Intake Path — Maintains a sealed connection between the air cleaner and intake, preventing unfiltered air ingestion that can accelerate engine wear and destabilize generator output.
- Fuel System Integrity — A cracked or collapsed air cleaner hose disrupts the air-fuel ratio on diesel generators, causing rough running, excess smoke, and potential engine damage — replacing it promptly restores proper combustion.
The air cleaner hose routes filtered air from the air cleaner housing into the engine intake, forming a sealed passage that keeps dust, debris, and unfiltered air away from internal engine components. On diesel-powered generators like the DCA125USI series, maintaining this seal is critical — any crack, split, or collapsed section allows unfiltered air to bypass the filter element, which increases wear on pistons, rings, and cylinder walls over time. A failed hose can also introduce air leaks that upset the engine's fuel metering, leading to rough operation and reduced generator performance.
