General guidance

Component knowledge

Understanding this component

In general, a connector in heavy equipment is a fitting or junction that joins wiring, hoses or other lines so they can be attached, separated and serviced as needed. The term "second type" usually indicates a variant within a catalog series rather than a confirmed function, so its exact design and role should be checked against the catalog.

What to check before ordering

Order using the existing part number 0016449, and confirm it against the catalog before purchasing. The recorded associations with the D350E fuel system filter and lines group are catalog occurrences only; check the serial number ranges and configuration conditions shown in the catalog to confirm they match your machine.
