Vacuum Line Cap Kit Black

The Vacuum Line Cap Kit Black by MOROSO is an essential accessory for any engine builder, mechanic, or performance enthusiast managing vacuum-operated systems. This kit is particularly useful when decommissioning emissions equipment or reconfiguring fuel pressure regulation systems, as it effectively seals open vacuum ports that could disrupt engine performance.

Crafted from durable black polymer, the Vacuum Line Cap Kit includes multiple cap sizes designed to fit a range of hose diameters commonly found in both domestic and import vehicles. The caps create an airtight seal by compression fitting directly onto vacuum hose barbs, eliminating the need for adhesives or permanent modifications. This ensures long-term chemical resistance to fuel vapors, heat cycling, and moisture, which is critical for reliability in modified engines.

Mechanics and engine builders rely on this kit for various applications, including carburetor conversions, EFI retrofits, and emissions-delete applications. Whether you're capping off a deleted fuel pressure regulator line or sealing an unused EVAP port, this kit provides the versatility needed for effective vacuum management in modified engine setups.
