But, install a fixed fuel line with a Racor between the tank and the engine. Don't install the fixed tanks too low or you'll need an electric fuel pump to get the juice to the engine. Finally, be careful of the plastic tanks. Some require you to install the hose fitting, and then you find out that you have a POS tank that leaks no matter how you install your hose fitting (I've got one out in the shed if you want it).
