- Pulley included: Ships with the pulley; supplied without a reservoir, reservoir cap, or filter.
- Extras: Includes a return pipe adapter and is sold without a core charge.

Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. AAE recommends flushing and filling the steering system with an OE-approved power steering fluid, and replacing the fluid reservoir when installing the pump, since a clogged reservoir can starve the new pump.
