Ssssh! Evil people are listening!
Ok, fuel pump power lead runs along the floor pan under the plastic trim. Remove trim, locate appropriate color wire, confirm you have the right wire, then install a discrete toggle switch on that wire mounted somewhere around the "B" pillar area so you can discretely flip it on/off when entering/exiting the vehicle.
Note: If you have small children mount it so they can't reach it, or it will be quite entertaining for them to flip it on/off while daddy is driving.
