a couple fuel system questions

I am getting ready to install an a1000 pump ran with a pickup tube, stock tank on a stock block turbo car. Do i need to run a relay switch with this pump and if so how big (30 or 40 amp?) Also, how big should the wires i run to operate the pump be...someone was telling me to run a ten gauge wire? And one more thing...should i prime this pump before i first turn the pump on or will it prime ok by itself?
thanks for any advice...

Where are you installing the pump? Intank, or external? If external, where? The farther away from the battery, the larger wire you will need. Or, as I did, use 2 relays, one that will trigger the other down stream so that the pump is close to the supply relay. Although my battery is in the hatch, so I am not all that far away from the pump.
It needs a relay for sure, 40Amp at the least, and it will be fine to prime it when installed and you turn the key, just cycle it a few times to make sure the pressure is up, and holds....

I ran 10 ga. to a relay in the spare tire well and tapped the stock fuel pump wire to feed the relay.
