Overview

How it works

Some GM fuel caps may include a check-valve that lets air in or out depending on tank pressure, aiding venting as needed. The GT347 is built to fit GM vehicles and maintain a dependable seal through everyday driving.

In daily driving, a properly sealed cap helps protect the filler neck from moisture and debris while keeping fueling predictable in varied weather conditions.

  • Daily commuting: predictable fueling and reduced risk of fuel exposure

As a GM OE replacement, the GT347 mirrors the original design and thread pattern, ensuring compatibility with GM vehicles that used this cap. It installs with standard hand tools and a snug fit.

  • Direct replacement for the original cap

Environment and efficiency notes
