I'll tell you, your heavy feed wire to the pump will fry all the way back to your fancy relay panel melting every other wire it's close to. How would I know that?

That's why everything gets fuses or a circuit breaker for protection. I've seen the burned wire to the fuel pump on cars before, no fuses and some had no relay. I don't class race and my battery is in the back. My fuel pump and it's relay are in the back also and both circuits to the relay are protected. Also my fuel pump ground goes directly to the battery, not a sheet metal screw into the floor pan.Nothing increases current draw like a bad ground.
