tends to be common to control fuel pumps via a relay - saves having the ECU switch (or send-to-earth) a high current load.
also, EFI pump relays often have a current limiter built in so the pump doesn't suck away precious power when you're idling or trying to start the engine. This tends to require two relays, one to switch power-to-pump on/off, the other to send current direct, or thru a big resister (current limiter).
also 2, by using a relay to drive the pumps, there's no fuse between the ECU and the relay, only betwen 12+ and the pump.
