S&B Tanks are made with the best quality high-density crosslink polyethylene. Being built from this material holds many advantages over metal fuel tanks. S&B Tanks will not rust, corrode or de-laminate over time. They also won’t have condensation issues and are more resilient than metal tanks. S&B pressure tests every single tank before they leave the factory. And with seamless installation, you don’t have to be a mechanic to install yours. S&B Tanks are designed to be installed in just a few hours.
