OE 6420920301 — Fuel Filter for Mercedes-Benz

Every shipment of 6420920301 leaves with a packing list, photo documentation and a QC report. Warranty terms are agreed per contract and reference that inspection record; claims are settled in writing against the documentation.

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest engine & fuel system reference and narrow by build year. Send photos and we will cross-check the number for you.

A supersession happens when the maker revises a fuel filter and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 6420920301 we list the current reference; ask our desk for written confirmation before a large order.

Position depends on the platform. On most Mercedes-Benz applications the fuel filter sits on the engine & fuel system assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 6420920301 with other engine & fuel system references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded fuel filter transfers stress to neighbouring components, so a small repair can grow into a full engine & fuel system rebuild. Book the replacement once the symptom is repeatable.
