MAXIMIZED CAPACITY

The Pulsefire backpack kit turns your handheld ignited fuel stream torch into a professional controlled burn system. A 3.3 gallon reservoir means an incredibly high capacity of real-world use. If you held the trigger nonstop, it would yield over 4 minutes of use before running empty.

COMFORTABLE & CAPABLE

The backpack is extremely manageable at only 26 lb with fuel. The slim design keeps the weight close and comfortable. This is the ultimate in controlled burn capability in a man-portable package.

Dude, Are you kidding me? As if the F'n flamethrower wasn't enough, now I have three gallons of playtime? This Big Dawg was the centerpiece of a fantastic 4th of July. Dudes were compensating spending thousands on fireworks, showed up by me and this reusable spectacle of American Testosterone. Big Dawg gotta eat, give 'em the 3 gallon. If you bought this flamethrower and don't have a backpack of dead dinosaurs spraying skyward to Lynyrd Skynyrd Freebird what are you even doing with your life? Happy 250 USA!

After a mistake on my end, The workers at Exothermic Tech helped me fix my error and for that I appreciate them I recommend buying any and all products for your torch systems. The UBF and backpack I own work flawlessly and fit in the case snug and secure Thank you Exothermic,

Love the tank giving me a longer burn time, however I had to reduce my rating by 1 star because the shoulder straps had to be reinforced after one strap ripped out the stitching and caused the tank to almost fall off of my back. Thank goodness I had a person behind me to catch the tank before it slipped off completely and drop to the ground.

The Tank is great quality and works well however the braided line causes stress on the connection going to the fuel pump this causes the fitting to strip and work its way free causing the line to leak. I'm on my 2nd fuel pump.
