These Saturns use a semi-returnless fuel system. Instead of sending tons of fuel to the engine it just sends it to the filter, which returns the unused portion and only about 10% goes to the engine. You have an inlet, a return, and an outlet to the engine. Only the engine fuel (outlet) is filtered, not the return to the tank. (If I remember correctly.)
The starter for a 1999 Saturn is on top of the transmission under the air filter box. Remove the filter box for easy access.
