Thinking about going back to mechanical

I see enough electrical problems at work, and avoid inviting any new ones into my life.
I love original Mopar electrical systems.
Even if I have a problem, there's like, what,
a dozen wires that really matter?
Plus, I am really annoyed by buzzing and whirring noises.
I've had mechanical pumps leak gas out the vent, quit working after 20 years, but have yet to have a diaphragm leak gas into the oil.
Did yours leak gas out the vent hole or not?
