Multiquip 11971759830 Fuel Injection Pipe 3TNV76 AR16-2

The Multiquip 11971759830 is a genuine OEM Fuel Injection Pipe 3TNV76 AR16-2 designed for the AR16-2 asphalt ride-on roller. As a direct OEM replacement, this pipe is manufactured to the exact specifications required for the 3TNV76 engine fuel system, ensuring a correct connection between the injection pump and injectors. Sourced directly through authorized Multiquip supply channels, part 11971759830 is the right call when accuracy and integrity of the fuel delivery circuit matter most.

Key Features

• OEM Fuel System Integrity — Manufactured to the exact bore diameter, wall thickness, and end fitting geometry of the original pipe, maintaining the precise fuel pressure required by the 3TNV76 injection system.
• Direct-Connect Replacement — Seats directly into the factory injection pump and injector ports on the AR16-2 with no rework or adapter fittings needed.
• Confirmed AR16-2 Fitment — Validated for the Multiquip AR16-2 asphalt ride-on roller equipped with the Yanmar 3TNV76 diesel engine.
• Consistent Injection Timing — A correctly seated, undamaged injection pipe maintains fuel delivery timing and volume, supporting smooth engine combustion and stable roller operation on the drum.
• Fuel System Safety — High-pressure injection lines that are cracked, corroded, or incorrectly fitted present a serious fuel leak risk; replacing with a genuine OEM pipe restores a sealed, pressure-rated fuel circuit.

A fuel injection pipe carries high-pressure diesel from the injection pump to each individual injector on the engine. On the 3TNV76 engine in the AR16-2 roller, this pipe must hold and transfer fuel at the precise pressure and timing the injector needs to atomize fuel correctly in the combustion chamber. A pipe that is cracked, kinked, or has deteriorated fittings will cause misfires, loss of engine power, or hard starting — any of which can bring compaction work to a halt. Replacing a damaged injection pipe promptly restores the closed, high-pressure circuit the engine depends on for clean, efficient combustion.
