A working hypothesis is that the impact sustained by WTC 7 from the collapse of WTC 1 resulted in fractures in the fuel piping system (both the fuel pipe and the containment pipe) especially at the point where the pipes entered the valve box, which was rigidly mounted to the underside of the floor slab. With the base system and all of the modifications thereto, such a fracture would result in a small leak of residual fuel in the pipes at the point of the fracture. A fracture of the pipe at the valve box would release fuel under pressure that, if ignited, could produce a spray fire and/or a pool fire very near column 79.

Take a look at this thread. It's near the end where all this fuel stuff comes out.

There's also Howard Roark's....I mean NIST's new speculation of the 12,000 gallons of fuel. The idea I think is that the lines for this fuel were surrounding the columns that failed? Is that correct?

Almost all of the fuel was recovered from some tanks, but not others.

Problem is, FEMA assumed the tanks were full on the morning of 9/11. If any of the diesel had been used before 9/11, obviously it would be "missing", and yet it seems it's automatically assumed to have caused WTC7's collapse.

Most of the fuel was recovered from the two base building tanks.
None was recovered from the SSB system.
Well there was the little detail from the interview with the person in charge of maintaining the systems. It seems that they had a contract with a fuel oil delivery company that specified that the tanks were to be kept topped off.

How do you know the tank wasn't empty already? This applies to all tanks that had any missing fuel. FEMA never went in before 9/11 and checked each tank; no one did, apparently. All that "missing" fuel could have just been used pre-9/11 and you wouldn't know the better.

Were they topped off on the morning of 9/11? Because there were suggestions in the FEMA Report that fuel started pumping as soon as the emergency situation presented itself, at several score gallons per hour or so.
