| Buy a relay like the one at this ebay link and run a 14-16 gage wire from the relay normally open contacts to the second fuel pump B+ and the car battery. Be sure to put a fuse in line close to the pump. For the relay coil to activate it, run one side to ground and the other side to the wire that feeds ECU pin 45. Now when you start the car the relay will feed the high current needed for the fuel pump directly from the battery via the relay.
