What tools does a person need to change a fuel filter in a 1993 f150. I see that the lines just plug into the filter and must be held on with some type of spring within the fuel line coupling. I don't have a repair manual where I am sure they tell you.

Here is the tool. You can find them at parts stores anywhere.
