Drain the tank: remove all fuel and residual debris, using an approved container or fuel caddy
To clean an auxiliary fuel tank, you must first drain the tank. This is a critical step in the cleaning process, as contaminants and loose debris, such as rust and sediment, can clog the filter, jam the turbine pump, or significantly reduce fuel flow due to build-up.
Start by removing all fuel from the tank. It is important to use an approved container or fuel caddy for this step to ensure safety and prevent spills. Some fuel tanks have a drain cock, which allows for neat and easy draining. If your tank does not have a drain cock, you can drain the fuel by removing a gas line or by siphoning it. Make sure to collect all the fuel in your approved container or fuel caddy.
Once the fuel is removed, there may still be residual debris in the tank. To remove this, you can insert a hose into the tank and begin pouring a stream of clean, hot water. While the water is filling the tank, spray a mild detergent inside to help loosen and remove any remaining debris. If the opening allows, you can also use a brush to scrub the sides and bottom of the tank, ensuring that all debris is loosened and captured.
After the tank has been cleaned with water and detergent, dump the dirty water into a pan, capturing any liquids, and wipe the tank with a lint-free washcloth. It is important to ensure that all fuel and debris are removed from the tank before moving on to the next steps of the cleaning process.
