It seems to me that batteries, alternatives and generators in cars would ave a stronger magnetic field than a cellphone. We know that the electrical system has enough charge to light a spark plug.
If they didn't the car wouldn't move forward.
I may be wrong but it seems that the car battery is able to live in harmony with the fuel lines.
