DIY Backpack Flamethrower Tutorial
Step One: Air Compressor
Start with an air compressor. You’ll want to remove the regulator, and fill in the space left behind with a brass plug.
Step Two: Tap Hole
Tap a hole in the bottom of the compressor to add fittings.
Step Three: Set Fitting
Your fittings should look like this with the correct valves.
Step Four: Run Hose From Valve
Run a hose from the valve and fit the end with an internal check valve.
Step Five: Connect Valve to Diesel
Connect the internal check valve to a diesel nozzle.
Step Six: Remove Spout and Add Pipe For Fuel
Remove the spout and add a pipe running down to a tip and hose as pictured. The tip and hose will run the fuel for your flame.
Step Seven: Tap Hose To Tank
Run a hose with a nozzle to a fuel tank tapped with a valve and fitting like this. Fill up your tank with tiki torch fuel! Add valve along the hose to better regulate your fuel.
Step Eight: Adjust and Test
Spark up and start throwing flames! You can adjust with the nozzles on the hose. The whole rigging will fit neatly into a backpack.
