Re: Size of wire??
The longer the wire the greater the resistance. Double the length of the wire and you double the resistance of the wire.
The larger in diameter the wire the less resistance in the wire. You can't go too big.
The resistance of the wire adds to the resistance of the circuit overall. As resistance goes up, current goes down.
12-14 gauge wire should be more than sufficient for a fuel pump in any race car. The smaller the gauge the larger the wire.
