Car Fix DIY Videos

In this video, I show you how to install a locking fuel cap on a Hummer H1, Humvee, or HMMWV—a simple but essential upgrade to help keep your diesel fuel tanks safe and secure from people tampering with them.

This cap is similar to the ones available from Predator and Mod Mafia, and installs in just minutes with no special tools. Whether you’re running in public, parking in questionable areas, or just want peace of mind, this is a smart and easy mod every H1 or Humvee owner should consider.
