How to: Check the Internal Hoses on EFOY Fuel Cartridges

  1. First, loosen the straps to get the tank out. Use the ratchet to loosen the straps.
  2. Gently lift the fuel cartridges up and out.
  3. Turn the tank upright (with the cap facing up).
  4. Shine a flashlight through the tank from the back. One of the hoses should go down to the bottom, the other should curve up. If there is just one hose, there’s an internal hose problem and we need a new fuel cartridge sent to replace this one.
