Road Racing - Accusump: How to Wire Solenoid?

How much current is required to run the electric solenoind version of the Accusump? I'm pre-wiring for a future install and would like to know the amperage the solenoid draws. What wire gauge and fuse, or would it be better to run a relay?

Thanks,

My advice
Would be to a run a cable pull with a manual valve for the accusump
