Electric water pump relay

[J-440]

I have the Meziere 300 series electric water pump for a 440 and was wondering if I need some type of relay in the harness. The pump right now is hooked into the fuse block under the hood, which is tied into the fuse box in the car, which is tied into the ignition switch. So when the key is in the run position, naturally the pump will be running. Do I need a type of relay similar to the one that is in an electric fan setup? Thanks again.
