How do you remove heater hose?

I have a pin hole size leak on a T-fitting that connects three rubber hoses. The T is located next to the brake fluid resevoir. The hoses that connect to it come from the firewall (next to the brake fluid resevoir), another hose comes from the water pump and the other attaches to the engine behind the upper radiator hose.
The hoses have some kind of metal end caps on them and I don't see any adjustment screws or anything like that to loosen them.

MY QUESTION IS...How do you remove these hoses so I can replace the T-fitting?
It is a 96 Vulcan

It would help to know what year and engine you have, but I have a hunch you have a tripodus butyl nofixus. If it is Ford's true to form latest hose design, it is a one piece monster with the metal tee permanently crimped onto the three rubber hoses. Your options are get a new one, solder it, glue it (some like JB Weld), cut off the bad tee and put in a new one with clamps from hardware or auto store. Be careful not to shorten the hoses too much if you remove all of the metal they might not reach the new tee. You may be able to put in a longer hose or hoses or splice things with more hose. I'd maybe consider cutting the old tee right at the joint and using short pieces of hose clamped onto the remaining metal tubes that are crimped onto the original hoses and then to the new tee.

I had that happen on my 98 Taurus LX. The leaks were on two metal hoses, on each side of the hoses they were connected to rubber hoses(IDK if this was factory or a fix from previous owners) So we bypassed the whole set up with a new rubber hoses on each one. At first I was skeptical, but It's going on 9 months, and it works perfectly fine.

In case someone reads this in the future I will post my solution.
My first choice was to replace the part with the original Ford hose part so I went to my local dealer and was quoted a price of $97.07 for the heater hose assembly.
The next day when I stopped laughing I took a closer look at the hose assembly on my car and realized there was enough extra hose to cut the crimped metal parts off of the hose and just replace the tee fitting. After searching several auto part stores I found a universal 5/8" x 5/8" x 5/8" tee at Napa Auto Parts (part number 660-1672) for $3.00. With the two additional clamps that I needed The total price came to $5.00. A far cry from $97.07. Plus it only took me twenty minutes to fix instead of a couple of hours if I replaced the entire hose assembly that goes through the firewall to the heater core.
If you cut something too short you can replace the piece of hose (about eight inches) that comes from the engine (behind the upper radiator hose) to give yourself some extra slack. But cut as close to the metal tee as you can and you'll be fine.
Good luck,
