Common Problems This Cap Can Address

• Loose or damaged fuel cap sealing surfaces
• Fuel vapor odor from a worn cap or venting issue
• Check engine light concerns related to evaporative emissions faults
• Difficulty maintaining a secure, lockable fuel tank closure
• Replacement needs after a missing or non-functioning cap

Installation Notes and Tips

Verify the cap style, thread diameter, and cam type before installation. This Gates 31836 fuel cap uses a Quick-On cam design and is specified as a regular fuel cap with emission control venting, so matching the original application is important for proper sealing and system operation.

For fitment verification, compare the vehicle listing to your exact year, make, and model. This is especially important on Ram, Dodge, Jeep, and Nissan applications where multiple fuel system configurations exist across model years.

Quality Assurance

Gates states that this locking fuel tank cap meets OEM specifications and Federal and State emission requirements. The pressure relief and vacuum relief valve design supports proper tank breathing while helping control fuel vapor escape.
