*** This is not a direct plug & play pump, some modifications maybe needed as it is a universal fit pump. The larger diameter at the base of the fuel pump will prevent this from being an OEM drop-in replacement on most applications. Modifications to the mounting bracket, wiring, and connector may be required for proper fitment.
