May 4, 2026. Cummins Clean Fuel Technologies (CCFT) announced a new internally designed and manufactured Type 4 compressed natural gas (CNG) tank developed to integrate seamlessly within CCFT fuel delivery systems for heavy-duty natural gas trucks. The tank will be introduced at the Advanced Clean Transportation (ACT) Expo, reinforcing CCFT’s continued investment in scalable, vertically integrated and high-performance fuel delivery systems for commercial vehicle applications.
Developed specifically for heavy-duty operations, the new tank features a fully carbon fiber-wrapped polymer liner engineered to reduce system mass while supporting the durability, lifespan, and integration demands of Class 6-8 applications. Designed as a critical element of CCFT fuel delivery systems, the tank enables optimized packaging, simplified installation, and improved vehicle efficiency.
“Fleets continue to evaluate natural gas as a practical and cost-effective pathway to lower emissions while weight and system efficiency remain critical considerations,” said Mike Zimmerman, President of Cummins Clean Fuel Technologies. “This new Type 4 CNG tank reflects CCFT’s focus on vertically integrated solutions that combine seamlessly into complete fuel systems while supporting payload capacity, uptime and long-term performance in demanding heavy-duty applications.”
The Type 4 CNG tank incorporates a fully carbon fiber-wrapped polymer liner construction with stainless steel bosses designed to enhance structural strength and long-term durability. The lightweight design supports increased payload potential and improved vehicle efficiency while meeting the performance requirements of heavy-duty truck applications.
