Multiquip 5154118710 Pipe Assembly Injection #4 DPS-130SST 4FB1

The Multiquip 5154118710 is a genuine OEM Pipe Assembly Injection #4 DPS-130SST 4FB1 designed for the DPS-130SST. As a direct OEM replacement sourced through Multiquip's authorized parts network, this assembly delivers the exact routing, fittings, and tolerances required by the 4FB1 engine's fuel injection system. Confirm your model code DPS-130SST before ordering to ensure a correct, first-time fit.

Key Features

• OEM-Grade Injection Line Integrity — Manufactured to the same pressure ratings and dimensional specs as the original, ensuring leak-free fuel delivery at the #4 cylinder position.
• Exact Routing and Connection Points — Pipe geometry matches the original assembly, so installation aligns directly with the 4FB1 injection pump and injector without rerouting or modification.
• Confirmed Fitment for DPS-130SST — Verified for the DPS-130SST submersible pump, keeping your parts selection accurate and your repair on schedule.
• Sustained Injection Pressure — A properly functioning injection line maintains consistent fuel pressure to the #4 cylinder, supporting complete combustion and engine output; a cracked or fatigued line causes misfires and power loss.
• Fuel System Safety Assurance — A compromised high-pressure injection line presents a fuel leak and fire hazard; this OEM assembly restores the integrity of that connection with a component built to handle the system's operating pressures.

The injection pipe assembly carries high-pressure fuel from the injection pump to the #4 fuel injector on the 4FB1 diesel engine. It must withstand repeated pressure spikes with every firing cycle without flex fatigue, cracking, or loosening at the fittings. When this line fails — whether through corrosion, vibration fatigue, or fitting wear — fuel delivery to that cylinder is disrupted, resulting in rough running, reduced power output, excessive smoke, or a hard-to-start engine. Replacing it with a genuine OEM assembly restores proper fuel metering and protects the wider injection system from cascading damage.
