Overview

The GM Genuine Parts GT358 Fuel Tank Filler Cap is a threaded cap crafted to seal your vehicle’s fuel filler neck. As a GM Original Equipment replacement, it mirrors the fit, performance, and service life you expect from General Motors. The cap includes a rubber gasket that creates a liquid-tight seal to keep fuel in and water or dirt out. Some versions may feature a check-valve to vent air as needed based on tank pressure.

Why this matters

A dependable fuel cap helps maintain a clean and efficient fueling system. By ensuring a tight seal, the cap can help prevent vapor release and protect the integrity of the filler neck, contributing to smoother daily fueling experiences and reducing the likelihood of contaminants entering the system.
