How does this cap restore proper function to my fuel system?

Installation is simple and typically requires no special tools. The cap is a user-replaceable component: remove the old cap, inspect the filler neck for damage, and thread the new cap on until it clicks or seats firmly.

• Mostly hand-installable—no mechanic required for most users
• Inspect filler neck gasket; replace if cracked or misshapen
• If a check-engine light lingers, allow the vehicle to run cycles; a diagnostic scan can clear codes
