Using this 4.5 - liter plastic fuel tank is quite straightforward. First, make sure you have your own mounting hardware to install it securely. Once installed, connect the fuel pick - up connection to your fuel system for drawing fuel. Connect the other connection for either venting the tank or returning unused fuel. When using, always keep the tank away from heat sources and open flames. To maintain it, clean the tank regularly to prevent debris build - up. Check the connections periodically to ensure they are tight and there are no leaks. If you notice any damage, replace the tank immediately for safety reasons.
