I had installed a Carter 4070 and there certainly are advantages for an electric pump.
However, I switched back to a mechanical because I felt it was safer. If there is a wreck, a mechanical fuel pump stops when the motor shuts off. Sure you can wire the electric pump to a oil pressure switch or impact sensor, but how many times have you actually seen that done? In most cases you'll be lucky to even see a fuse, much less any sort of automatic shut off.
Also, sometimes an unwitting driver may leave the ignition switch on rather than use the accessory position when listening to tunes. I've had to replace the ignition coil three times. Each of my three sons had had to learn the hard way by sitting, doing who knows what with the engine off, with the ignition in the on position. So, sometimes drivers may do that, and I really don't like the idea of a pressurized fuel line all that time without the engine running. In fact I've seen a case where someone did that, and a leaky needle valve let the carb overflow and filled the motor with gas.
I'm not the only person using our cars. In our family it could be any family member at any time. That's how we roll.
I just can't have a car that's not safe.
It's my logic, and my family.
