Apparently, USS Arizona had been fully refueled before the attack.
Last year Mrs. S in CA and I visited Pearl Harbor. Due to high demand, visits to the memorial are limited to ~10 minutes, and the boats ferrying visitors to the Memorial are busy all day long. I seriously wish the visits could be longer, but it was designed ca. 1960 when anticipated visitorship was less than at present. If you go there, head as quickly as courteous and practical for the room with the list of men killed on the Arizona, so as to hear all of the docent's presentation.
Also, take a bus over to Ford Island to see USS Missouri, BUT ... near the parking lot is another memorial. It is a colonnade of pylons for each sailor lost on USS Oklahoma. Both the memorial wall on the Arizona Memorial and the Oklahoma Memorial given the names of the fallen in simple alphabetic order, sailors mixed with officers mixed with admirals. There is also a memorial for USS Utah, but it was closed while we were there.
Between the memorials and the Missouri one can span the beginning and the end of the Pacific War. Sort of chronologically in between, in the area where one will wait for the tour boat for the Arizona, one can tour the Submarine Museum and Balao class submarine USS Bowfin, and there is a plaza with a circle of memorial markers for each of the 52 submarines lost in WW2.
