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

DESCRIPTION:

The fuel filter is one of the most overlooked maintenance items on a Sprinter diesel — and a restricted filter is one of the most direct paths to injector damage, pump wear, hard starting, and rough running. This Hengst OEM fuel filter is the correct replacement for 2004–2009 Sprinters with the OM647 2.7L inline-5 and the early OM642 3.0L V6 (non-DEF). Keeping this filter fresh protects every downstream fuel system component from contaminants that accumulate over time.

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.

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. Always prime the fuel system after installation to purge air from the lines before starting the engine.
