Installation Notes and Tips

Confirm the vehicle’s year and fuel system configuration before installation. This pump is for in-tank use and uses a hose outlet with chip-style terminals, so connector and line routing should be verified against the original unit. The listing notes fuel strainer inclusion for the applicable fitments, and no wire harness or regulator is included.
