EFI isn't a bad way to go. It does present a possible road side scenario I guess if you happen to have an important sensor fail.
I have mine setup for certain scenarios just in case. As grivera mentioned I run a trap door in the trunk literally making fuel pump swaps a 30 minute deal.
I also keep a open loop tune in the program so the car runs without an O2 sensor. So if that fails and AFR's go wonky I simply load that tune and drive away.
Other sensors like TPS or CTS probably won't leave you stranded but keeping spares are easy enough if you desire.
Keep in mind the need to change an in tank pump is extremely rare. Millions of cars on the roads today use them, in fact I'd bet everyone here has a car in the fleet with it and don't even think twice about it. So this shouldn't be a huge concern for anyone really.
02 sensors can occasionally fail but if installed properly I find that to be a rare issue as well. They usually have problems when horrible tuning practices are used, bad placement, things like that.

I don't believe EFI should be considered a solution for other problems one is having like this whole fuel issue. As I've stated many times both of our dailys are carb and points and simply don't have these problems. EFI in many cases I've seen come through here have their own new problems, primarily from horrible installs, terrible fuel system setups, wiring that looks like a rats nest, 99 percent of this stuff being self inflicted. Which helps me to understand why one had carb problems in the first place lol.
Unfortunately it then gives EFI an undeserving bad rap. But EFI is pretty nice when done properly.
