Mercedes-Benz G-Class Fuel Filter Replacement Parts

Yes, the G-Class has a fuel filter, though where it sits and whether it is a serviceable external unit or integrated into the fuel pump assembly depends on the engine and generation of the vehicle. Diesel variants (such as those running the OM602, OM606, OM647, OM642, and later diesel codes) have a clearly separate, replaceable fuel filter, while petrol variants may use a filter that is less accessible or integrated within the tank unit. When requesting a quote from a breaker, tell them your engine code as well as your registration, as this is the detail that will identify the correct filter type.

The W460 ran from 1979 to 1991, the W461 is the military and commercial variant that continued alongside, and the W463 is the civilian luxury series that launched in 1989 and ran through to 2018 before the W464 arrived — these generations use different engines with different fuel delivery systems, so the filters are not the same. Even where engine families overlap in name, ancillary components including filter housings and connections can differ between platforms. Confirm compatibility with a breaker against your exact registration and engine code rather than assuming a W460 or W461 part will cross over to a W463.

Engine code is the single most important detail for fuel filter fitment on the G-Class, because the same model year was sold with multiple engine options — for example, the W463 was available with different petrol and diesel straight-sixes and V8s at various points, each with its own fuel system layout. Matching by year alone risks getting a filter designed for a different engine entirely, which may not physically connect or filter to the correct specification. Find your engine code on your V5C or via a VIN check and give it to the breaker alongside your registration.

Trim level and AMG designation do not affect fuel filter fitment directly; what matters is the specific engine code fitted to your vehicle, which on AMG models will be a high-output variant such as the M113, M156, or M176 depending on the generation. Because AMG engines differ mechanically from standard petrol units, the fuel filter or fuel delivery components may also differ, so you still need to supply the engine code to the breaker rather than just the AMG badge name. The trim level itself — whether standard, AMG Line, or full AMG — has no bearing on filter fitment.

The W463 ran until 2018 and the W464 (the heavily revised generation) launched that same year with a substantially updated platform, new engines, and revised fuel systems, so the two generations are not interchangeable for fuel system parts. Even if an engine family name looks similar across the two generations, ancillary components and mounting arrangements may have changed at the generational boundary. Ask a breaker to confirm fitment against your exact registration and engine code, as this is the safest way to establish whether a donor vehicle is close enough to supply the correct part.

Within the W463 generation (1989–2018) there were several diesel engines used at different points, including straight-six and V6 units with different engine codes, so the filter from one year may not suit another even within the same body generation. Year proximity alone is not a reliable guide — the engine code printed on your V5C or obtained via a VIN check will tell a breaker immediately whether a specific donor vehicle is a match. Mounting and ancillary changes mid-production are also possible, so always confirm the exact part against your registration with the breaker before purchasing.
