Installation Notes and Tips

Verify the vehicle uses a mechanically driven vacuum pump before ordering. Confirm the barbed connector style, 1/2 in inlet, and the absence of a pulley, gasket, seal, and relief valve against the original part. Because fitment varies by engine and configuration, compare the existing pump to the vehicle application before installation. Professional installation is recommended for proper sealing and vacuum system operation.
