Check the 1991 Legacy for a stuck thermostat. Check to make sure that the water pump is working properly.
ok 1990-1994 subaru legacy engines are basically the same the water pump on mine 1991 is located on the thermostat housing on the bottom of the engine on the lower tube off the radiator so find your lower radiator hose follow it is should go to the thermostat and the water pump is on that
It means that the gasket seal on the water pump is bad and you need to replace it before you drive the vehicle.
The fuel pump on a 2002 Subaru Legacy is located inside the gas tank.

A local library may have the repair manual.
The fuel pump relay on a 1991 Subaru Loyale is located on the driver's side of the engine compartment. It is part of a bank of relay switches on the fender wall and right next to the Self Test Connector which is the last location on the far right.
