My curiosity got the better of me and I tore apart my dead elec. fuel pump. I know my 67 250se sat for at least ten years as the state inspection sticker is from early 94. The pictures attached show how the small amount of unspent gas in the pump had turned to a consistency of taffy. I believe I killed the pump when I tried to turn over the motor the very first time. The thick coagulated fuel destroyed the brushed and caused the motor to over heat and melt some parts and fuse others (the alum. impeller is welded to the casing). The debris shown in the picture, which resembles parts of a cockroach, is a melted plastic that is used under the brushes.

Lesson learned: it pays to stabilize your fuel anytime you park your for an extended time.
