21776807 Fuel Tank Cap — Volvo FH12 FH16

This fuel tank cap seals the fuel tank, preventing contamination and vapor loss from the fuel system. It is constructed from durable materials to withstand harsh operating conditions and maintain a tight seal, unlike a worn cap that may not secure properly. Operators may notice fuel odors or a check engine light related to evaporative emissions if the cap is failing.

Failure Symptoms

A loose or damaged fuel tank cap may allow fuel vapors to escape, leading to a noticeable fuel smell around the vehicle. If ignored, this can result in increased fuel consumption and trigger an evaporative emission system fault code. The ultimate consequence is potential environmental non-compliance and reduced fuel efficiency.

Installation Tip

Ensure the sealing surface on the fuel tank filler neck is clean and free of debris before installation. Do not overtighten the cap, as this can damage the threads or the seal.

Service Note

Inspect the fuel filler neck for any damage or corrosion that could prevent a proper seal.
