Where are you referring to?
The braided lines? Those are High pressure oil, and yes there is a tool to unlock the quick disconnect.
Ken(Woodnthings) had a great post with some info on the HPOP lines. https://www.ford-trucks.com/forums/1...l#post11336134

No you shouldn't have to remove the Y-pipe if we are talking about the High Pressure oil Lines. Here is a write-up from Clay

There is no special tools required to remove the nut on the fitting but the easiest way to reach it is to remove the air intake assembly from the valley. This the the aluminum air flow director that has the 4 boots attached to it that is commonly called the 'spider' assembly. Once it is removed, it is an easy reach to go under the turbine housing and remove the nut. This is a compression type of connector that uses a special elastomer sleeve that is compressed similar to a copper tubing compression fitting. The elastomer compression sleeve will become hard and cracked with time and heat. The only thing you can do to repair it is to replace it with a new sleeve after cleaning all remnants of the old sleeve from the brass nut. The new sleeves are soft and flexible and will easily slip over the flare on the end of the tubing. Then just re-tighten the brass nut, compressing the sleeve until the brass nut just barely touches the fitting body.
We do have the new sleeves available at our store.

If it's the HPOP line it is oil, there are fuel lines that run down the passenger's side head though as well, but they will be hard lines.

That is the line Bob (Diesel o-rings) above mentioned to you. Unless the line itself isn't leaking from the hold down clip area you can reuse that line and install a new sleave from Bob in the back like I did, better service and a heck of alot cheaper than Ford. I did mine for preventetive maintence and I'm glad I did, mine was beat, brittle. While your at it just replace the other side sleave or o-ring, can't remember going to the fuel bowl and be done with that side. Welcome to FTE by the way..

Just replaced mine the other day, as well...used 1 from first pic. Worked great to remove the old-brittled ones.

If the fuel sleeve is stiff and stays inside the nut, hook the sleeve with the pick to hold it in place and "unscrew" the nut off the sleeve. Works alot easier than trying to dig it out.

Glad you found it, it's actually pretty common... Here is a link to the Failure Prevention Thread might help keep things in check!

Here is a diagram of the fuel lines to add to this thread. It will hopefully help reduce confusion later on. Item 19 is the line that rubs through.
Here is the clamp that causes the damage.
And the fix by wrapping it with a thick tape (self adhesive tape)
