    Gas tank size - 1960 5.5HP Seahorse

    Hi everyone, I am waking up a 5.5HP old seahorse and need to buy a new gas tank. Would it make sense to go with 3 gallon gas tank and 5/16 fuel line? I was debating between the 3 gallon and 6 gallon gas tank. The engine will be mounted to a 12 foot boat. Thanks, Russ
