As a factory-sourced assembly, EE49319 delivers an exact match to the original fuel system components, ensuring correct installation without adaptation or guesswork. This assembly is the right call when a full fuel system replacement is needed on QSB5-equipped machines, covering the complete set of fuel delivery components in a single kit.

Key Features

• Genuine OEM Fuel System Integrity — Factory-sourced assembly matched to Cummins QSB5 fuel delivery specifications, ensuring correct flow rates and biodiesel compatibility throughout the system.
• Biodiesel-Compatible Construction — Purpose-built to handle biodiesel fuel blends, with seals, lines, and components rated for the chemical properties of biodiesel operation.
• Complete Assembly Replacement — Replaces the full fuel system as a single unit, simplifying service and ensuring all interdependent components are refreshed together.
• Direct Fit for QSB5-Equipped Machines — Engineered specifically for Cummins QSB5-powered Multiquip equipment, installing directly in place of the original assembly.
• Protects Engine Performance — A correctly functioning fuel system maintains consistent fuel pressure and clean delivery to the injectors; a degraded system risks poor combustion, hard starts, and engine damage.

The fuel system assembly manages the complete delivery of fuel from the tank to the engine's injection system on Cummins QSB5-powered equipment. It encompasses the components responsible for filtering, pressurizing, and routing fuel so the engine receives a clean, consistent supply at the correct pressure. When any part of this assembly degrades — whether through contamination, wear, or biodiesel-related material breakdown — the result can be rough running, power loss, hard starting, or injector damage. Replacing the full assembly restores the fuel system to original operating condition and protects the engine from the downstream effects of fuel delivery failure.
