Have a leak in one of the rear heater lines on my 93 GC. According to the Haynes manual I have it doesn't seem too complex (it says disconnect at tee fittings in engine compartment, push on connectors at rear). Is it that straight forward and are the lines a dealer only item?

TIA for any help.

Cut out the bad sections and replace with high quality heater hose and screw clamps.
The metal tubes are dealer items, supposed to be improved, around $600 installed.

That's kind of where I was leaning towards anyway. Any idea what the diameter of the lines are? The Haynes book doesn't say. Rough guess looking at the line I'd say maybe 5/8 I.D. hose line is needed?
