I have a '93 Delta 88, so here's guessing it's in the same spot. Look under
the car on the passenger side, just behind the front wheel. You should be
able to see the black plastic fuel line almost in the middle of the car. If
you follow it, it turns up at about a 45 degree angle, into the "tunnnel"
over the transmission, where it then continues into the engine compartment.
The filter is located part of the way up. On my car, it's hiding behind the
power steering fluid cooler - a miniature radiator - that is easy to unbolt
from the chassis.
