The Sierra 18-4008 Block-Off Plate from Holley is a crucial accessory for any automotive enthusiast working on a Mercury engine. This plate is specifically designed to replace the factory vacuum port found on Mercury engines, providing a clean and neat appearance by blocking off the unused port.

Crafted from high-quality aluminum, the Sierra 18-4008 Block-Off Plate boasts a durable and robust construction that ensures longevity and reliability.

The Sierra 18-4008 Block-Off Plate is engineered to fit Mercury engines with a 18mm vacuum port. The plate features a threaded hole, which accommodates a 18mm x 1.5 NPT male fitting (sold separately), allowing you to connect various vacuum accessories, such as fuel pressure regulators, vacuum gauges, or other vacuum-related components.

Installing the Sierra 18-4008 Block-Off Plate is an effortless task, thanks to its user-friendly design. Simply remove the factory vacuum port gasket and bolts, replace them with the new plate, and secure it in place using the provided hardware. The plate's O-ring ensures a perfect seal, preventing any vacuum leaks and maintaining optimal engine performance.
