Fuel Filler Neck

Browse New OEM fuel filler neck pipes and housing components for GM vehicles including Cadillac CT6, Silverado, Sierra, and other models. Our factory-original fuel filler components are sourced from GM surplus — the exact tube diameter, routing angle, and rollover valve configuration for your application.

A cracked or corroded fuel filler neck allows fuel vapors to escape and can cause fuel spillage during fill-up. OEM replacement necks provide the correct anti-rollover valve function and vapor seal required by your vehicle's EVAP system.

Verify part numbers against your vehicle's fuel tank configuration and filler tube routing before ordering. Contact us for fitment assistance.
