I am working on a Daewoo/Doosan D30S-3 forklift with a 4cylinder B3.3 Cummins engine. I ordered new after market fuel injectors for it. When they came i unpacked them and compaired them to the old ones. the old ones have a cone shaped copper washer where it seals in the head. the new ones have a flat copper washer.I checked with the dealer and they gave me this part number. (DWA-333222). When i look that up on line i cannot find any pictures of it. Any body have any ideas ?
These are pictures of the copper washers.
