The Multiquip M1373101003 Flexible Air Filter Hose is a genuine OEM component designed for DCA45USI4CAN and DCA45USI2 ultra-silent diesel generators. As a factory-sourced part, it meets the original design and material standards that Multiquip engineers specified for these machines. This hose is a direct-fit replacement, confirmed for the DCA45USI4CAN, DCA45USI4CAN (FR), and DCA45USI2 generator models. Keeping this component in good condition is essential to maintaining clean, unobstructed airflow to the engine.
Key Features
- Genuine OEM Construction: — Manufactured to original Multiquip material specifications, ensuring the hose retains proper flexibility and sealing characteristics under continuous engine operation.
- Direct-Fit Replacement: — Engineered to connect directly to the air filter assembly with the same routing and end fittings as the original, allowing a straightforward swap without fabrication or adaptation.
- Confirmed Fitment: — Compatible with DCA45USI4CAN, DCA45USI4CAN (FR), and DCA45USI2 ultra-silent diesel generator models.
- Maintains Clean Airflow: — A structurally sound hose prevents unfiltered air from bypassing the air filter, protecting the engine from dirt ingestion and premature internal wear.
- Fuel System Integrity: — Proper air metering through an intact hose supports correct air-fuel ratio, contributing to stable engine output and efficient fuel combustion on the DCA series generators.
The flexible air filter hose channels air from the air filter assembly into the engine intake, forming an airtight connection that ensures only clean, filtered air reaches the combustion chamber. Over time, this hose can crack, harden, or develop loose connections due to heat cycling and vibration — any breach in the hose allows unfiltered air to enter the engine, accelerating wear on internal components. Replacing a damaged hose with a genuine Multiquip M1373101003 restores the integrity of the air intake path and keeps the generator running at its designed performance level.
