OK I'll buy that, I was just working off previous posts and I'm by no means an expert of any kind on anything that happened on 9/11. It sounds like they haven't ruled out the possibility of fuel contributing to the fire though. From your post :

Fuel System for Emergency Power in WTC 7
• NIST has reviewed and documented the fuel system for emergency power in WTC 7
• Floor 5—which did not have any exterior windows and contained the only
pressurized fuel distribution system on the south, west and north floor
areas—is considered a possible fire initiation location, subject to further data
and/or analysis that improve knowledge of fire conditions in this area.
• The two 6,000 gallon tanks supplying the 5th floor generators through a pressurized
piping system were always kept full for emergencies and were full that day.
• Both tanks were found to be damaged by debris and empty several months after the
collapse. Some fuel contamination was found in the gravel below the tanks and
sand below the slab on which the tanks were mounted, but no contamination was
found in the organic marine silt/clay layer underneath.
• This finding allows for the possibility, though not conclusively, that the fuel may have
contributed to a fire on Floor 5.
