Product Overview

The fuel filter, OEM number 8981596930, is the diesel fuel filter element fitted to the Isuzu D-Max II 2.5 CRDI and 2.5 CRDI 4x4, and the related NKR77 and NLR87 truck models with the 4KH1 engine. Since this filter spans both the D-Max pickup and the NKR/NLR light truck range, it's a genuinely high-turnover part for anyone stocking Isuzu diesel service items.

Worn or clogged units typically show up as rough running, a noticeable loss of power, or hesitation under load. GSK Auto manufactures this fuel filter element 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.

(Confirm against your VIN or chassis code before ordering - this filter spans both D-Max pickup and NKR/NLR truck applications, so it's worth double-checking the exact model and engine before ordering at volume.)

What Is a Fuel Filter?

Function: The fuel filter removes dirt, rust, and other contaminants from diesel fuel before it reaches the high-pressure fuel pump and injectors, protecting these precision components from damage caused by particulate matter.

Working Principle: Fuel passes through the filter's pleated media as it's drawn from the tank, trapping contaminants while allowing clean fuel to continue on to the fuel pump and injection system.

Importance: On common-rail diesel engines like the 4KH1, fuel cleanliness is critical, since the high-pressure pump and injectors operate at tight tolerances that are easily damaged by contamination.

Common Failures & Signs: Clogging from accumulated debris restricting fuel flow. Rough running or misfiring linked to contaminated fuel reaching the injectors. Noticeable loss of power, especially under load. Hesitation or hard starting caused by restricted fuel delivery.
