Replacing the vacuum hose firewall grommet on a 1968-1982 Corvette C3? This direct replacement helps you get the correct appearance and reliable function without hunting for a used part.
Product Highlights
Why this 3-Hole Grommet matters
- Prevents vacuum leaks that can affect brake boost, PCV system, and overall engine performance by maintaining a stable hose seal through the firewall.
- Organizes multiple vacuum lines with a single, integrated grommet, reducing wear from movement and minimizing routing confusion during maintenance.
- Protects hoses from firewall edges and heat exposure, extending hose life and reducing the risk of cracks or abrasion.
- Maintains a cleaner engine bay appearance with a neat, factory-like pass-through that respects the Corvette’s classic lines.
Installation tips
- Remove old grommet and inspect the firewall edge for cracks or damage; replace if necessary to ensure a proper seal.
- Clean the firewall surface before installing the new grommet to maximize seal integrity.
- Route the vacuum hoses through the designated holes, ensuring hoses aren’t twisted or kinked, and verify that all connections are snug.
- Recheck fit after engine bay reassembly and test vacuum-operated components to confirm there are no leaks.
