Standard use is either clamp it around the hose ir insert the tool into the connector and push both tool and hose towards each other usually you have to wiggle it a little bit it should pop loose fairly easily.
open the tool, slide it over the line and into the groove between the two sides. push and twist it to release inside tabs. pull apart
You have to drop fuel tank and use quick disconnect tool to change lines
Ford fuel lines use a unique line coupler. You'll need to purchase a disconnect tool, but fortunately they are relatively inexpensive and can be purchased at most auto parts retailers.
Easy use a quick disconnect tool or a small screwdriver
the line is a quick disconnect to operate your tool is to simply open it up place it on the line with the stems facing the connector and push in on the tool once the tool is fully seated keep pressure on the tool while pulling on the line to remove it. good luck
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.
insert a quick disconnect tool into the coupler , the same tool you would use to disconnect fuel lines.
The connection on the engine side of the filter is a metal collar quick-connect fitting. You will need to use a special tool called a "fuel line separator tool" available at most auto parts stores to disconnect this fitting. You insert the fuel line separator tool into the female side of the fitting, push it into the fitting until it releases the locking tabs inside the fitting, and then pull the lines apart.
There is a special tool to remove the fuel line from the filter on Rangers/Explores. I bought mine at Autozone for around $10.
You can use a very small flat blade screwdriver if you know what you are doing.
located by gas tank use a fuel line tool
Use a siphon hose inserted into the tank. To get the remaining fuel out or if your vehicle has an anti siphon device you will have to disconnect a fuel line and turn on the key. This will activate the fuel pump and fuel will flow from the line.
