WJI500040 - Land Rover Element - Fuel Filter

Land Rover Defender Fuel Filter – WJI500040 (Puma 2.4 & 2.2 TDCi)

WJI500040 is the spin‑on diesel fuel filter element fitted to late‑model Land Rover Defender Puma (TDCi) engines, covering both 2.4L and 2.2L. Installed in the engine‑bay fuel filtration module, the filter performs the essential function of removing fine particulates and water contamination from the diesel supply before it reaches the high‑pressure common‑rail system.

Genuine Land Rover filters are supplied as a black, spin‑on canister with a metallic threaded head and factory‑printed fitting instructions. Each unit incorporates high‑efficiency filtration media rated for modern common‑rail tolerances and is manufactured to OEM quality standards. Visual identification includes the printed part number WJI500040 and Land Rover branding.

The filter is used across Defender 90, 110 and 130 TDCi vehicles from VIN 7A000001 onward and forms part of the routine service schedule, typically requiring replacement every 12,000–24,000 miles depending on operating conditions. Frequent changes are recommended where vehicles operate in dusty, humid or contaminated‑fuel environments, as degradation of the filter can lead to restricted flow, reduced power, hard starting and potential injector wear.
