Product Overview

The fuel filter, Hengst reference E445KP D314-2, is a filter insert fitted to the Mercedes-Benz Actros MP4/MP5, Antos, Arocs, and Travego (O 580) heavy-duty truck platform, along with the Setra 400 and 500 bus series. As a routine maintenance item on widely used Mercedes-Benz commercial truck and bus platforms, this filter sees consistent, repeat demand from distributors and workshops servicing commercial fleets.

A worn or clogged fuel filter typically shows up as reduced engine power, hard starting, hesitation or stalling under load, or in severe cases, fuel system damage from unfiltered contaminants. GSK Auto manufactures this fuel filter to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is a Fuel Filter?

Function: The fuel filter removes dirt, rust, and debris from fuel before it reaches the engine, protecting fuel injectors and other precision fuel system components from damage.

Working Principle: Fuel passes through a filter media inside the housing, trapping contaminants while allowing clean fuel to flow through to the engine. Over time, trapped debris restricts fuel flow and reduces filter efficiency.

Importance: On a heavy-duty truck and bus platform running long daily mileage, a properly functioning fuel filter is essential for reliable engine performance and protecting expensive fuel system components from premature wear.

Common Failures & Signs: Reduced engine power or acceleration. Hard starting or difficulty starting the engine. Engine hesitation, sputtering, or stalling, especially under load. Increased fuel consumption from restricted flow.
