Charcoal cannister compatibility

[rucraig]

Hi,

I'm talking to an eBay seller about a charcoal cannister from a 1994 e420. The link to the ebay item is:

Does anyone know whether this part # 124 470 08 59 is compatible with my '92 500e. I believe the correct/original part # for my vehicle is 124 470 03 59.

Thanks in advance for any assistance.

Stand down folks - figured it out - this part superseded the one in my car and will fit

1244700859 does not exist in the EPC or MB systems. I think that it's the part number stamped on the canister housing, and the new part (1244700359) is sold as an assembly (maybe with a bracket or something). Canister appears NLA new.

Beware of used ones, they often have defective internal screens which allow carbon particles to exit the canister, and plug up the purge valve, causing a large vacuum leak. You can add a filter inline with the tubing to keep the valve clean.

Thanks. What type of filter would you recommend?

Something similar to what you see below. You might need to search for "fuel filter", as the same type of filter is used on small engines (garden tractors / lawn mowers). Just needs to have the right size fittings for the hoses. Install the filter on the opposite side of the "MOT" port, on the canister side, with the flow arrow pointing towards the MOT/engine side.
