The Multiquip M1311500803 is a genuine OEM Intercooler Hose Upper designed for DCA36SPXU4F and DCA45SSIU4F series super-silent diesel generators. As a direct OEM replacement, this hose is manufactured to the same specifications as the original component, ensuring a correct, secure connection within the intercooler circuit. Sourced directly from Multiquip, part M1311500803 is the same part your generator left the factory with, giving you full confidence in the replacement. Compatible models include DCA36SPXU4F, DCA45SSIU4F, and DCA45SSIU4FC8 configurations.
Key Features
- OEM-Matched Hose Construction — Manufactured to the same internal diameter, wall thickness, and bend geometry as the original, ensuring airtight sealing under turbocharged boost pressure.
- Direct Drop-In Fitment — Engineered to connect directly between the intercooler and intake tract without trimming or adapting, using the same clamp positions as the factory installation.
- Confirmed Compatibility — Verified fit for DCA36SPXU4F, DCA45SSIU4F, DCA45SSIU4FC8, and related 60Hz super-silent diesel generator variants.
- Maintains Charge-Air Efficiency — A sound upper intercooler hose preserves the cooled, compressed airflow that the turbocharger delivers to the engine; a cracked or collapsed hose causes power loss, rough running, and excessive exhaust smoke.
- Fuel System Safety — A properly seated intercooler hose prevents unmetered air leaks that can affect air-fuel ratio, protecting the engine from lean-running conditions and potential overheating under load.
The upper intercooler hose carries compressed, pre-cooled charge air from the intercooler to the engine intake manifold on turbocharged diesel generators. By reducing the temperature of the pressurized air before it enters the combustion chamber, the intercooler system allows the engine to produce more power efficiently and run cleaner. When this hose cracks, collapses, or loses its seal at either end, charge-air pressure drops, combustion efficiency falls, and the engine may exhibit reduced output, increased fuel consumption, or difficulty sustaining load — making timely replacement essential for generator performance.
