AEU2147L - Land Rover Cartridge-diesel fuel filter

Land Rover 200Tdi / 300Tdi Diesel Fuel Filter - AEU2147L

AEU2147L is the cartridge‑type diesel fuel filter used on Land Rover Defender, Discovery 1, and Range Rover Classic models fitted with the 200Tdi and 300Tdi engines, spanning production from the late 1980s through the mid‑1990s. Installed within the engine‑bay fuel filter housing, this replaceable element cleans diesel prior to entry into the injection pump, removing particulate contamination that can cause wear, blockages, or premature failure of the injection system.

Supplied in a cylindrical steel canister with an upper sealing gasket, genuine Land Rover versions of AEU2147L feature OE‑grade filter media packed into a robust shell, ensuring consistent filtration efficiency and correct fitment within the sedimenter/filter head.

Engineered for the fuel‑delivery system of Tdi‑powered vehicles, AEU2147L forms a critical safeguard against debris, rust, water and fine particulate matter commonly found in diesel storage tanks. By maintaining fuel cleanliness, the filter helps preserve injector performance, stabilises idle quality and protects the high‑pressure pump from internal scoring or cavitation. As part of routine maintenance, the filter is typically replaced at each major service interval, and symptoms such as reduced power, hard starting or excessive injection‑pump noise often indicate restriction from a clogged or contaminated element.
