The Multiquip M3373100403 Flexible Air Filter Hose is a genuine OEM component designed for DCA150USJ3CAN and DCA150USJ2 ultra-silent diesel generators. As a direct Multiquip OEM part, the M3373100403 is manufactured to the same specification as the original, ensuring a proper connection between the air filter assembly and the engine intake. This hose is confirmed to fit the DCA150USJ3CAN, DCA150USJ3CAN (FR), and DCA150USJ2 models, making it a straightforward service replacement for technicians and operators maintaining these units.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specification, with hose material and wall thickness matched to the factory air intake routing on DCA-series ultra-silent generators.
- Direct Connection Fit — Designed to seat correctly at both the air filter housing and engine intake ports, restoring the sealed airflow path without improvised adapters or modifications.
- Confirmed Fitment — Verified for DCA150USJ3CAN, DCA150USJ3CAN (FR), and DCA150USJ2 ultra-silent diesel generator models.
- Maintains Clean Air Delivery — A properly seated flexible hose prevents unfiltered air from bypassing the filter element, protecting the engine from particulate ingestion and sustaining generator output under load.
- Flex-Design Durability — The flexible construction accommodates minor positional variance in the air intake system and resists cracking from vibration and heat cycling typical of continuous generator operation.
The flexible air filter hose routes filtered air from the air filter assembly into the engine's intake system, forming a sealed, vibration-tolerant connection between the two components. If this hose cracks, collapses, or loses its seal at either end, unfiltered air can enter the engine, accelerating internal wear and causing erratic engine performance. On a generator operating at sustained load — as DCA-series ultra-silent units commonly do — a compromised air intake hose can also contribute to fuel efficiency loss and elevated exhaust emissions, making prompt replacement an important part of routine service.
