There is typically a fuel pump relay of some kind. On the carb models I beleive it's just the solid-state relay in the fuel pump control unit that does the job. There might be another but I would have to consult my FSM diagrams.

I had an intermittent problem with my fuel pump in my 81 Brat. Ended up being a loose and corroded ground next to a relay under the driver's seat. Dunno that that is the fuel pump relay for sure, but that ground seems to be connected to the pump, and I can't imagine the point of any other relay being in that location.
