Question on fuel pump wiring. I'm using a Holley 12-132 in tank pump pic below:

I run 12awg wires from the relays to the pump then they eventually meet the smaller gauge wires at the pump.

Confirmed when the engine is running that 15 amps is being drawn by the pump.

The smaller wires are very hot after a couple of minutes. So hot that I can't touch them.

To me, the wires are too small at the pump, but why would Holley produce a pump with that smaller gauge wire ?

I am using a hydramat inside the tank to suck up the fuel. Could the hydramat be causing the pump to work harder ? But if that was the case, wouldn't the amperage be higher too ?

Any help from the experts as to why the wires are very hot would be much appreciated!
