If youve got an electric fuel pump and a carb equipped older muscle car,personally ID run a 10 ga copper wire along the frame and connect it to a dimmer switch I installed under the carpet, up out of the way but accessible with your toe (if you know where to push) so stepping on it would start and stop it providing power to the pump,so it will give you a bit of extra security in that you can make it far more difficult to steal your car, and its not obvious that you are turning on/off the fuel pump
obviously you can get the factory shop manual and make the connections just like the factory pump if you choose too, so the pump comes on when the keys used to start the car,having a lead that only goes hot once the ignitions on, is a better option for most guys so its best to connect to a power lead supply that only goes hot once the ignitions on and remember to push the button to activate the pump, or de activate it as you, enter or exit the car, but either way the cars fuel pump will not run when the keys off, if you get absent minded, and you have the option of de-activating the pump if you park the car for extra security,

yes if you connect the feed directly to the battery but youll need to REMEMBER to start and stop the pump circuit or you'll run the battery dead, or the car won,t start until you remember to turn on the pump IF you turned it off,when you exited the car but having a hidden switch , makes it so you can park the car, and anyone even if they take your keys in a car jacking wont get all that far, PROVIDED you make it a habit to touch the switch as you exit the car (just an option)
(having a small light on the dash under the fuel pressure gauge that indicating power to the pump wired into the circuit helps, you remember to turn on the pump)
