personnaly the first time I started with oldies (10hp) and 2 line tanks I would park my tilted trailer to drain rain water out the boat and one dayI found that 5 gal of gas had drained out also.
A small rusty pin hole under pressure gave way and out came the fuel during a hot summer day.
Conclusion: 2 line tanks are fine just like one line tanks but keep and eye on the bottoms. I was lucky my drain plug was out and the fuel went into the grass ( no tgood for worms, grass and water table) but at least I did not go up in smoke.
