You could get a device to measure stray charges in your tank, or just spend the 15 dollars on the ground probe and be covered should the need arise. I would recommend it, and recommend that it is PROPERLY hooked up. There is one made that plugs right into a 3 prong outlet, with the 2 main prongs being plastic, that is the easiest one to buy, and assuming your box is grounded properly you should be fine with that one.
