Chip, the more I read, the more I felt for you! What an experience! At
least when I've rolled, it's been over in a few seconds, sounds like you
had to agonize for several minutes watching your "loved one" get
crispy! Good luck with the fix up. Thank God for safety equipment.
Think I'll make sure my fuel pumps turn off when the car is shut off for
any reason.
