In the tank. Lift the trunk floor and you'll find a round cover about 8" in diameter. The fuel pump(s) is/are there and attached to a rubber cone shaped surround with a jubilee clip. The whole assembly lifts out as a unit.

Given that yours is a '90, I expect it to have a Walbro pre-/main pump set up rather than the single Bosch unit. Both are interchangeable as a complete assembly IIRC.
