>OK, now will someone remind me as to why this wasn't the likeliest cause of TWA 800?

A few reasons
1) All pumps were found and examined except one.
2) The mounting positions of the pumps showed no signs of deflagration (fire)
3) The source of the fire was shown to be internal and away from the pump locatiions.
4) There was not a similar known batch problem with the pumps as identified in todays problems
5) JBS says it can't be the tank it must be a door and he's an expert isn't he?
