2nd fuel tank. That is one of the reasons I want to add the aux rear tank. I would set it up with a selector valve, instead of as a transfer tank. Then I would have a built in spare in case mine does go. I'm almost at 360,000 miles and the fuel pump is still factory, so I'm sure its only a matter of time...
For emergency use, even a small (7 gal?) fuel cell could work if you don't have space for the rear tank. Worst case you could siphon fuel from the not-working main tank and refill the fuel cell. With this setup you could just plumb it through an external fuel pump, and even use a mechanical switchover valve (2 of them actually since there's also a return lie). Main downside it you would have to remember to cycle that fuel periodically before it goes bad.
