the fuel pump relay is under the dash, it is usually named a Mitsuba or similar.

it has a 8 pin connector,

looks like:

you hook it up using the following connections:

If your using OBD1, pins A7 and A8 are used to run the EFI fuel pump, thru the main relay pictured above. If for some reason, your car stalls or your in a crash etc, pins A7 and A8 will cease to draw power and the fuel pump will cease to get power, this stops the fuel pump feeding an engine bay fire.
The pics posted are pretty self explanatory, just a case of working out which wire is which.

Fuel pumps do run continuously, that is what your fuel pressure regulator is for. The fuel that is pumped up and not used is returned to the tank from the pressure regulator.
