Question on this, somewhat related.

What is the advantage of two separate tanks and a switch between them? And instead of replacing two separate tanks with one big one, couldn't you just plumb the two together with a really big, nonrestrictive hose? I'm thinking 2", or something that would be sure to absolutely not hinder flow, but joins the two together, then you only ever draw from one of the tanks but it ultimately pulls from both. Make sense? Am I missing a critical part of something?

The big advantage of separate tanks is fault tolerance. Yes, the tank switch can fail, and either sender can fail. But a failed sender does not leave you stranded. And more likely than a failed switch is a tank leak, esp. with Ford's :idiot: design of using the skid plates as rear tank supports. This creates a perfect place for road crud to build up and rust the rear tank, right on the bottom. So when it rusts through, you retain NO fuel. If you had just one large rear tank, and this happened, (1) you'd lose more fuel, and (2) you'd have no backup.

If you have only one tank, what will you do when you get some contaminated fuel in it? A large balance tube is just a great place for the leak that empties both tanks and leaves you stranded.
