Remove fuel tank and replace sending unit.. May as well do fuel pump while your there, and change the fuel filter.

Take out the sender from the tank and clean it. If it's too corroded buy a new one. If you can't find a new one you will have to buy one from a scrapyard or adapt an older Ford one .

Usually when there is a black, ashy coating on the spark plugs, this indicated that the engine is running rich. This can be caused by a few things, including a faulty coolant temperature sensor that may be indicating a cold engine when it's in fact warm. A bad oxygen sensor can also cause some engine enrichening as well. These are just a couple of things you may want to check.

Please let me know if you need any further assistance. :)
