We ended up idling for over half an hour when trying to leave the Casa de Fruta
rally, so I have a log I can play back with EBL. According to its calculations,
we burned slightly over 1/4 gallon in 30 minutes, so should be a bit over 1/2 gallon
per hour with our fuel injected (tbi) 455. Whether that's accurate or not depends on if our
injector calculations are really correct. I had them flow tested, but who knows.
Based on very limited at-the-pump experience, I think they're close-ish.
