I can get free access to the Chilton Library online through my public library. Before I moved, I had free online access to the Auto Reference Data Center. So you may want to check with your local library to see if they offer something similar.
Chilton's says, for '98, that the 2.0l engine's fuel pump can be accessed through an inspection hole cover located beneath the rear seat. For the 3.0l, there may be an access panel under the rear seat. If not, Chilton's notes that you have to drop the tank. For the 4.1l engine, you can get to it by removing the "trunk room finish panel".
