The Multiquip 1552143100 Filter Cup Assembly is a genuine OEM component designed for DLW400ES, DLW400ESA, and DLW400ESA1 series diesel light welders. As a direct Multiquip OEM part, it is manufactured to the exact specifications required for the D1403 and V2203 engine configurations found in this equipment family. Sourced through DHS Equipment, this assembly ensures you are installing the correct part the first time. Confirm your model code against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications for the filter cup assembly, ensuring proper sealing performance and fuel system integrity.
- Direct-Fit Replacement — Engineered to seat and secure exactly as the original, with no reworking of mounting points or fuel line connections on the D1403/V2203 engine platform.
- Confirmed Fitment — Compatible with DLW400ES, DLW400ESA, and DLW400ESA1 diesel light welder models; verify your model code before purchase.
- Fuel System Protection — A correctly functioning filter cup assembly maintains a clean, sealed fuel delivery path; a cracked, degraded, or improperly fitted cup can introduce contaminants or cause fuel leaks that interrupt engine operation.
- Fuel System Safety — Fuel system components require correct fitment and sealing to prevent leaks; using the OEM-specified assembly supports safe, compliant operation of the welder in the field.
The filter cup assembly houses the fuel filter element and forms a sealed chamber within the fuel delivery system of the engine. It allows fuel to pass through the filter media while containing particulates and protecting downstream components such as the fuel pump and injectors from contamination. When the cup cracks, warps, or fails to seal correctly, fuel leaks or unfiltered fuel can reach the engine, leading to hard starts, rough running, or premature wear of precision fuel system components.
