The XM42 Polymer Backpack Fuel Tank in Gray (XM42 part no. XM42-BPT) is a 2.5-gallon reservoir built for extended runs with a compatible XM42 flamethrower. Its polymer body keeps overall weight down while staying durable through repeated use, and a black braided hose delivers a secure, flexible fuel line between the tank and your flamethrower. Padded, adjustable straps make the backpack comfortable to wear for extended sessions, so you’re not stopping to refuel every few minutes. It’s a practical upgrade for anyone who has outgrown their flamethrower’s standard onboard tank.
