I need to remove Fuel line from engine when changing my spark plugs, do i need a special tool?

Is there like a special tool i have to put in place before removing the fuel line from the engine? I have to remove it because the spark plug is right underneath it. If i do pull it out, is it possible to get air in the lines?
Its a 99 Mustang GT.

if you’re talking about the fuel line attached directly to your fuel rail then you might need a special tool to remove it depending on what type of car you have. Some cars just have a little clip that you can easily unclip, but for a lot of cars youll need a fuel line disconnector, which is essentially just a little adapter piece that you insert into the line and it pushes on the clips holding it in place without breaking them. Don’t try to do it with a screwdriver or anything else becuase you most likely WILL break those clips, the adapter piece is not expensive and its not hard to find.
Just one note is, before disconnecting the line be sure you’ve depressurized the system or else youll have gas spewing out the end (there is always pressure in the system even when the engine is off).
To do that you can just disconnect your fuel pump and then run your engine until it stalls out to burn up all the gas in the lines. try to start it a couple of times after it stalls and make sure it wont start before disconnecting your fuel line.

  2. before removing it release the pressure off the line. you might need aline wrench so you won,t round the head on the line. after you get done, put the line back on and there is a small valve on the fuel rail you push to bleed the air out.
