How do you use the fuel line tool to disconnect the fuel filter in a 1999 ford ranger?

Answer 1

There are little metal fingers inside the line that snap behind a ridge on the fuel filter inlet and outlet tube. The purpose of the tool is to spread those fingers outward. What you have to do is, clip the tool over the filter tube with the cone aimed toward the line. Slide the cone of the tool into the end of the line and press it completely into the line as far as it will go. It sometimes helps to push the line and the filter together somewhat as you push the tool up into the line, and then pull the line off of the filter. It can be a little tricky, but once you get the hang of it, it's not that hard.
