How to: Seal a fuel tank
THERE ARE MANY REASONS YOU NEED TO SEAL A fuel tank. Steel tanks often suffer from rust and corrosion getting into the petrol and blocking fuel systems, or worse, water sitting in the fuel for years while stored and corroding the tank completely. Glass fibre tanks can also suffer, especially from ethanol damage. Plastic tanks are not immune either, with some modem tanks swelling from modem fuels. You may need to replace an existing sealer, as there could be splits, or rust could have formed underneath. You can change the rubber hoses and even carburettor floats; but tanks need to be sealed.
