I am attempting to replace the fuel filter on a 97 Explorer XLT with 83,000 miles. The filter has never been changed before. I purchased the fuel line removal tool from Autozone and tried to disconnect the lines to replace the filter. The tool is the correct size and slides into the opening but will not disconnect the line. Is there any special instructions I need to follow and should I try to spray the opening with WD-40 or some other type lubricant?
Thanks in advance, Ron Munroe Falls, Ohio
