The XM42 Lite to Ultralite Backpack Conversion Kit (XM42 part no. LITE-CONVERSION-KIT) is the hardware needed to run your XM42 Lite handheld flamethrower off the larger Ultralite backpack fuel reservoir instead of its standard onboard tank. Made by XM42, the same team behind the original XM42 handheld flamethrower line, this kit swaps in the fittings needed to route fuel from the backpack tank to the Lite’s ignition system. It’s built for owners who already run an XM42 Lite and want longer continuous burn time without stopping to refuel. Pair it with the XM42 Ultralite Backpack reservoir to extend a single session well beyond the stock tank’s capacity.

Key Specifications

• Compatible with the XM42 Lite handheld flamethrower, letting it draw fuel from a backpack reservoir instead of its onboard tank.
• Functions strictly as a fuel-routing adapter, not a standalone tank or flamethrower.
• Requires the Ultralite Backpack reservoir, sold separately, to actually extend fuel capacity.

Frequently Asked Questions

Does this kit include the backpack reservoir? No, it only converts the XM42 Lite’s fuel connection so it can accept the separately sold Ultralite Backpack reservoir.

Will this work on the standard XM42 or XM42-X? It is designed specifically for the XM42 Lite; check with the manufacturer before pairing it with another XM42 model.
