One more thing to check regularly...
Just had the fuel filter replaced on my 94 Taurus wagon because the
filter had rusted through and was leaking gas.
I bought the car used. Could have been the orignal filter, and this is
around salty Boston. The car has been looked after by good mechanics
while I've owned it for the last year and some months, but they never
saw the problem coming... and I'm old enough, and it's cold enough
around here, to think that $55 ain't bad ($16 for the filter, rest in
labor), even though that's getting to be a significant percentage of
the car's total value...
You'd think these would be engineered to resist rust. They're under
pressure and they're open to the elements, under the car.
(Gotta admit the body integrity of this car is pretty good. There was
never any gas odor inside the passenger cabin).
