In general, an adapter is a fitting that connects two components that do not match directly, such as different thread sizes, port types or connection styles. In engine fuel systems, adapters help route fuel or fluid lines between pumps, injectors, filters and manifolds. The exact role and fitting type of this specific catalog item should be checked against the catalog entry.
Use part number 0307977 when referencing this adapter. Before ordering, compare the catalog occurrences shown on this page with your engine model, serial number and the surrounding fuel-line arrangement, since listed associations do not confirm fitment for every machine configuration.
