The PulsefireA(R) Backpack Kit transforms your compatible handheld ignited fuel stream torch into a high-capacity, professional-grade controlled burn system. Designed for extended operation and serious outdoor applications, this kit dramatically increases runtime while maintaining comfort, balance, and reliability in a fully man-portable package. At the core of the system is a 3.3-gallon fuel reservoir, delivering over 4 minutes of continuous burn time if operated nonstop-making it ideal for prescribed burns, large brush clearing, perimeter ignition, and other demanding fire-starting tasks. The reservoir supports gasoline or gasoline-diesel mixtures, providing flexibility without the need for specialty fuels. Despite its increased capacity, the backpack remains highly manageable. With fuel, the system weighs approximately 26 lb, and its slim-profile design keeps the load close to the body for improved balance and long-term comfort. Durable materials including aluminum and Viton components, combined with a powder-coated finish, ensure long service life in harsh outdoor environments. A robust 6.5-foot PTFE-core hose with stainless steel braid and SS304 JIC fittings provides secure, reliable fuel delivery while allowing excellent freedom of movement. Precision fittings and a sealed fuel outlet maintain consistent flow and dependable operation throughout extended use.
