Removing the alternator and reaching in from the front also gives you a surprising amount of maneuverability between the upper and lower intakes. It's time consuming, but it really opens everything up. You can get your whole arm in there and get some leverage.
If you want to go for the nuclear option, though, just cut the hard pipe off and order a new one from Toyota. They're less than 40 bucks from McGeorge (23801-66020) and order new banjo bolt while you're at it. You can get to the other end by loosening up the TB and main wiring harness where it mounts to the firewall.
