Goofy heater hose connections Chevy GMC

[Lynn]

Less than a year ago I replaced the heater hoses on my 04 Yukon XL Denali.
I believe they are the same from 98 through 2014, so there have to be a few million of these out there.

Because it has rear heat/AC, there are extra "T" fittings on each of the heater hoses going into the firewall.

Have a very small drip.

Is there a permanent fix to this goofy-ass setup?

I realize why they designed it this way (assembly line), but stuff like this is really frustrating.

I know there are stainless steel adapters that push on and then you just clamp a heater hose to them.

But, then there is no provisions for plumbing in the rear heat (no "T").

Anyone find a solution?
