The Multiquip 8973148610 Fuel Suction Pipe DCA25USI 4LE2 is a genuine OEM fuel suction pipe designed for the DCA25USI ultra-silent diesel generator. As a direct OEM replacement, this pipe is manufactured to the same specifications as the original component, ensuring a correct fit within the fuel delivery system of the DCA25USI. Sourced directly through authorized Multiquip supply channels, this part is backed by the confidence of genuine OEM quality. If you are servicing a DCA25USI unit, verifying this part number against your machine's parts manual is always recommended before ordering.
Key Features
- Genuine OEM Fuel System Integrity — Manufactured to OEM specification for the 4LE2-powered DCA25USI, ensuring correct internal diameter and material grade for consistent fuel draw without leakage or restriction.
- Direct Drop-In Replacement — Engineered to connect at the factory-defined pickup point within the fuel tank assembly, so installation follows the same routing as the original component.
- Confirmed DCA25USI Fitment — Designed specifically for the Multiquip DCA25USI ultra-silent diesel generator series equipped with the Isuzu 4LE2 engine.
- Uninterrupted Fuel Delivery — A correctly functioning fuel suction pipe maintains steady fuel flow to the injection system; a cracked or degraded pipe can introduce air into the fuel line, causing hard starts, rough running, or generator shutdown under load.
- Fuel System Safety — Replacing a deteriorated suction pipe with a genuine OEM part eliminates the risk of fuel seepage near the engine compartment, supporting safe operation of the generator in enclosed or sensitive environments.
The fuel suction pipe is the component responsible for drawing diesel fuel from the bottom of the tank and delivering it toward the fuel injection system. It sits submerged within the tank and relies on a secure, airtight connection at both ends to maintain consistent suction pressure. Over time, the pipe can crack, harden, or develop pinhole leaks due to prolonged fuel exposure and heat cycling — any breach in the line allows air to enter the fuel circuit, which disrupts injection timing and can cause the generator to lose power or fail to start. Replacing a worn pipe promptly keeps the 4LE2 engine's fuel supply stable and the DCA25USI performing at rated output.
