Not Ranked
Livnn,
I don't know SPF, but as no one else is jumping in to help you, I'll offer this. According to the Holley site, the blue pump draws 3 amps, which is not very much. If the circuit (and switch if you use one) is rated for 3 or more amps, you should be able to wire it direct without a relay.
