Overview

The GM Genuine Parts GT139L locking fuel cap is a genuine GM original equipment replacement designed to seal your vehicle's fuel filler and safeguard the tank environment. A durable rubber gasket creates a liquid-tight seal to help keep fuel contained while keeping water and dirt out. Some variants include a check-valve to balance air flow with pressure changes inside the tank, contributing to steady fueling behavior.

Locking security and durable design

The built-in lock adds a practical layer of theft deterrence, while the cap’s construction is built to withstand regular use and exposure to engine bay conditions. As an OEM-grade part, it is designed to mirror the performance and service life you expect from General Motors.

Key benefits

  • Vehicle-specific fit that aligns with GM vehicle designs for reliable operation
  • Rubber gasket delivers a liquid-tight seal to help prevent leaks and ingress
  • Check-valve option (where included) aids pressure balance during fueling and venting
  • Locking mechanism provides theft deterrence while maintaining easy access when needed

Practical notes for daily use

  • Easy replacement that complies with GM factory standards
  • OEM-recommended part supports consistent fuel system behavior
  • Compact, vehicle-specific design fits under most filler hatches without modification
  • Backed by the GM Genuine Parts heritage of quality and availability

When you install this cap, you choose a component designed to perform like the original. It is intended to complement the vehicle’s fuel system integrity and does not alter other functions. Consider this cap as a thoughtful upgrade or replacement option for GM owners seeking reliable, OEM-grade parts.
