Installation Notes

Verify inlet and outlet connections before installation, including the MQC inlet and threaded M14-1.5 outlet. This pump uses a bolt mounting style and does not include mounting hardware or a wiring harness. Confirm vehicle-specific fitment by year and model before service, especially on Chevrolet Malibu, Chevrolet Impala, Buick Regal, and Chevrolet Malibu Limited applications.
