Replacing Fuel Cartridges: A Step-By-Step Guide For Beginners

how to replace fuel cartridge

Replacing a fuel cartridge is a simple process that can be done by following a few easy steps. This guide will take you through the process of replacing an EFOY fuel cartridge, including how to reset the fuel level in the controller so it knows the tank has been replaced. You will also learn what to do if you have a fuel tank left over, and how to dispose of an empty fuel cartridge safely.

How to disconnect the tank from the fuel hose

To disconnect the tank from the fuel hose, first make sure the tank is empty by comparing the amount of fuel in the cartridge that’s empty to one that is full (tanks are semi-transparent). If the tank is totally empty, replace it with a full tank and throw the empty tank away or recycle it.

Next, push down the release mechanism to undo the straps holding the tanks down. Unscrew the large cap to disconnect the tank from the fuel hose. Set the new, full tank where the old tank was by carefully lifting it with both hands and gently lowering it between the two metal brackets.

Once you replace the tank, you need to reset its fuel level in the controller so it knows the tank has been replaced. You must perform a reset on each cartridge you replace.

How to dispose of an empty fuel cartridge

To dispose of an empty fuel cartridge, first make sure the tank is empty by comparing the amount of fuel in the cartridge to a full one. Tanks are semi-transparent, so this should be easy to do. If the tank is totally empty, replace it with a full tank and dispose of the empty tank. Do not throw away empty fuel cartridges with the fuel adapters still attached. Remove the fuel adapter before throwing away the empty cartridge. Follow the MSDS from SFC to safely dispose of the empty cartridge.

If you have a fuel tank left over, put that tank in the camera storage box. Push down the release mechanism to undo the straps holding the tanks down. Unscrew the large cap to disconnect the tank from the fuel hose. Set the new, full tank where the old tank was by carefully lifting it with both hands and gently lowering it between the two metal brackets.

You will then need to reset the fuel level in the controller so it knows the tank has been replaced. You must perform a reset on each cartridge you replace. If the EFOY had run out of fuel completely and displays an error 20/22, press the reset button on the front panel to clear the error.

How to reset the fuel level in the controller

To reset the fuel level in the controller, you must first replace the fuel cartridge. To do this, make sure the tank is empty by comparing the amount of fuel in the cartridge that’s empty to one that is full (the tanks are semi-transparent). If the tank is totally empty, replace it with a full tank and throw the empty tank away or recycle it.

Next, to reset the fuel level in the controller, follow these steps:

  • Move the ignition switch to the 'ON' position.
  • Access the 'ODO' mode of the Odometer by pressing the 'Trip/Odo' button.
  • Stop the engine and turn off the ignition.
  • While holding down the 'Trip/Odo' button, turn on the ignition switch.
  • Hold down the 'Trip/Odo' switch for approximately two seconds.
  • Press the 'Trip/Odo' button three or four times, then hold it down for four to five seconds so that the levelling information displays on the Odometer.

If the EFOY had run out of fuel completely and displays an error 20/22, press the reset button on the front panel to clear the error.

How to verify the tank you replaced

To verify the tank you replaced, you can look at the fuel hose connectors, which are labelled '1' and '2'. If you had not reset the controller yet, the screen would say '0%'. After resetting the controller, the screen should say that the cartridge is full.

Before replacing the tank, you should make sure it is empty by comparing the amount of fuel in the cartridge that's empty to one that is full. Tanks are semi-transparent, so you can see the fuel levels. If the tank is almost empty (fuel percentage on the EFOY controller is below 10%), replace it with a full tank.

If you are replacing a fuel sending unit, you should inspect the top of the unit for any damage and/or corrosion, and that it is seated correctly in the tank. If the top of the unit is dirty, clean the connectors to help conductivity. Make sure there is a good ground connection as well. To verify the fuel sending unit is receiving proper voltage, set the multimeter to 20 volts. With the battery turned on, back-probe the input connector on the sending unit and check for voltage. Refer to the Service Manual for the proper voltage. If the input voltage is lower than the volts called for, inspect the wiring from the sending unit to the battery as it could be faulty.

How to store a leftover fuel tank

To replace a fuel cartridge, first make sure the tank is empty by comparing the amount of fuel in the cartridge that’s empty to one that is full (tanks are semi-transparent). If the tank is totally empty, replace it with a full tank and throw the empty tank away or recycle it. If you have a fuel tank left over, put that tank in the camera storage box. Push down the release mechanism to undo the straps holding the tanks down. Unscrew the large cap to disconnect the tank from the fuel hose. Set the new, full tank where the old tank was by carefully lifting it with both hands and gently lowering it between the two metal brackets.

To store a leftover fuel tank, it is recommended to keep your tank half full. The safest place to store gasoline is in the tank of your car. You should also store your fuel tank in a well-ventilated location to prevent the buildup of gas fumes. Fuel vapours can expand and contract due to temperature fluctuations, so it is always a good idea to vent your gas cans when storing them. If you are storing diesel, it should be stored in approved yellow fuel cans in a cool, well-ventilated place or in above-ground tanks. The shelf life of diesel is 18-24 months, which can be extended almost indefinitely by annually adding a quality fuel stabiliser.
