Bob -- at issue is that PDX is located behind a levy from the Columbia River. Thus, it's all "bottom land" and in a flood plain. I don't know how the airport does it (or Hertz for that matter), but I think that commercial gas stations don't want to deal with the possibility of having their tanks underwater in a flood.
The nearest gas stations are (1) on NE 122nd, south of Airport Way, about 4 miles SE of the rental car return or (2) on Sandy Blvd just east of the 205 Fwy (about 4 miles also, east on Airport, South on 205, east on Sandy from PDX). Number one is probably easier to get to and from, number 2 has a few more stations to choose from.
Remember also that with the laws changing in New Jersey, Oregon is the only state where you can not legally pump your own gas...

It took me 6 miles away from the airport to a station that was closed so, after wasting 30 minutes I went back to the airport and paid for the refueling.
Be aware and gas up before you leave where ever you are staying.
