Does the Ford fuel line disconnect tool work?

 

Yes. You might have to use the 3/8 tool instead of the 5/16. And, there might be some road gunk up in there. I spray some WD40 up there to loosen up the stuff then a long small blade screw driver or something similar to knock out any pebbles or whatever might be in the way. They need to be pretty clean to get the fuel lines out.
