" Ford has a better idea "
Sorry just had to say it , exact replacement heater hose would only be available from Ford. If they still supply parts for your 19 year old chassis, they're only required to supply parts for 10 years.
The aluminum , crimp clamps , can be cut off with a dremmel or similar tool and replaced with standard hoses & clamps , brass "T" should be available from your auto parts store 5/8" should be the size.
I can't tell from the second photo if there are quick disconnects at the heater core, that require a special tool , similar to A/C lines.
You can cut the heater hose and remove the " T " and practice removing the " crimp clamps " on the bench , before you go after the ones on the heater core.
