Detailed Description

Designed for direct replacement use, the Spectra FN772 helps restore the fuel fill path on trucks that need a new filler neck due to corrosion, damage, or leakage at the neck assembly.

What It Helps Fix

  • Fuel odor caused by a compromised fill assembly

Installation Notes and Tips

Verify year, make, model, and fuel system routing before installation. Compare the original filler neck shape, mounting points, and hose connections to the FN772 before removal. For Chevrolet Silverado and GMC Sierra trucks, confirm the exact application against the vehicle’s build details to ensure proper fitment.

Quality Assurance

Spectra Premium states that its engineering, manufacturing technology, and quality control processes are used to produce fuel filler necks that meet or exceed original equipment performance for the applications they replace.
