Additional Fuel Tank?

[joe7670]

OK, have an 87 cuddy with a 60 gallon tank. Replacing tank and wondering if it's worth putting in another tank somewhere.

In case you haven't seen my other posts, floor from cuddy to transom is currently out.

Probably going to run a 150 motor and wondering if 60 gallong will be enough.

Also, if I add one where would be the most logical place to put in my model. My 60 gallon tank is in middle in between the front seats as it was a full transom sea drive model.

Anyone have some literature or info on how dual tanks get plumbed?
