Mercedes Sprinter Diesel Fuel Filter – Hengst OEM | OM647 2.7L & OM642 3.0L | #6420920101 (2004–2009)

A clogged or neglected fuel filter is one of the fastest paths to injector damage, pump wear, hard starting, and rough running on a Sprinter diesel. This is the Hengst OEM fuel filter for 2004–2009 Sprinters equipped with the OM647 2.7L inline-5 or the early OM642 3.0L V6 (non-DEF), a direct replacement that keeps every downstream fuel system component protected from contamination.

What This Part Does
The fuel filter removes particulates, water, and contaminants from diesel fuel before it reaches the high-pressure injection pump and injectors. On common rail diesel systems like the OM647 and OM642, fuel system cleanliness is critical — injector tolerances are measured in microns, and even minor contamination causes accelerated wear, poor atomization, and injector failure. A clogged filter starves the pump of fuel flow, reducing rail pressure and causing power loss, rough idle, and hard starting.

✔ OEM-Style/Direct-Fit Fuel Filter
Hengst-manufactured filter built to OEM specification for a precise fit on OM647 and early OM642 fuel systems.

✔ Restores Fuel System Protection
Removes particulates and water before fuel reaches the injection pump and injectors, protecting micron-tolerance components from contamination.

✔ Built for Durability & Easy Installation
Direct bolt-in replacement — always prime the fuel system after installation to purge air from the lines before starting the engine.

When to Replace
Replace the fuel filter every 20,000–30,000 miles under normal conditions, or sooner on vans exposed to poor-quality fuel, high duty cycles, or heavy loads.
