changed the filter twice ... i guess i failed to mention that.
i also failed to mention that i suggested that she get the filter changed again after i did it for her because the gas looked like sh*t-water ... literally! she never did.

anyway on the day the car died, when she called me from illinois and described what the car was doing, i told her to buy a filter and have it changed. she did.
from what i was told, when they towed it back after she set out the last time, they pulled the line again and the gas looked like sh*t-water ... in the space of about 10 minutes. i've never seen that before. that's why i was wondering about the condtion inside of the tank.
anyway, thanks for the replies. i appreciate them all.
