Northern Tool has a big selection of gravity feed. Mine is a 50 gallon toolbox tank combo. Gravity feed has worked flawlessly.
I think this is my aux tank I bought.
While gravity feed will work "Great" - it does have a drawback. I don't think it will comply with the latest EPA guidelines on fuel vapor escape from the fuel system. Also there might be a problem in a accident, where fuel can escape. So I don't know if they can be installed anymore.
TransferFlow is spending a lot of money to make the systems with fuel pumps to transfer the fuel from your second tank to the main tank, and monitor the fuel levels in both tanks for a reason, compliance with Federal Laws.
TransferFlow has a link to the laws on their website.
