The Multiquip 8972323341 is a genuine OEM Gasket Leak Off Pipe DCA25USI 4LE2 designed for the DCA25USI ultra-silent diesel generator. As a direct OEM replacement, this gasket is sourced from Multiquip's authorized parts supply chain, ensuring it meets the exact specifications of the original component fitted at the factory. This part is confirmed for use on the DCA25USI series, so you can order with confidence knowing you're getting the correct part for your machine.

Key Features

• OEM Fuel System Sealing Integrity — Manufactured to the precise compression and material specification of the original gasket, ensuring a leak-free seal on the leak-off pipe junction of the 4LE2 diesel engine.
• Direct-Fit Replacement — Engineered to match the original mounting interface on the DCA25USI, dropping into position without rework or modification to surrounding fuel system components.
• Confirmed DCA25USI Compatibility — Specifically applicable to the Multiquip DCA25USI ultra-silent diesel generator powered by the Isuzu 4LE2 engine.
• Prevents Fuel Leak-Off Line Seepage — A worn or degraded leak-off pipe gasket allows diesel to seep past the connection, leading to fuel loss, contamination, and potential engine running issues. This replacement restores a clean, dry seal.
• Genuine Multiquip OEM Part — Supplied as an authentic Multiquip component under part number 8972323341, backed by the OEM parts program for traceability and quality assurance.

The leak-off pipe gasket seals the connection between the fuel leak-off pipe and the engine's fuel injection system on the Isuzu 4LE2 diesel engine. Its role is to prevent excess fuel — returned from the injectors at low pressure — from escaping at the pipe fitting. When this gasket degrades or fails, fuel can seep externally, creating a potential fire hazard, reducing injection system efficiency, and causing the engine to run inconsistently or emit the smell of raw diesel during operation.
